Technical modeling of the assembly - data

The following data are the direct effect of a engineering simulation. Values were calculated on models for the material Nd₂Fe₁₄B. Actual parameters may differ. Use these calculations as a reference point for designers.

Magnetic force weakens sharply with every subsequent millimeter of distance. Remember that even a very thin break (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnetic products work optimally in perfect adhesion; gap nullifies the force. See how quickly the parameters plummet, when the magnet does not adhere tightly to the metal substrate. When planning the assembly, eliminate unnecessary gaps.

The following data shows the theoretical force sufficient to cause the slippage of the magnet downwards along a vertical steel wall (considering standard friction). The holding force varies with the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 70x50 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	50.46 kg / 111.25 lbs 50463.0 g / 495.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	33.64 kg / 74.17 lbs 33642.0 g / 330.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	16.82 kg / 37.08 lbs 16821.0 g / 165.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	84.11 kg / 185.42 lbs 84105.0 g / 825.1 N

When placing a holder on a vertical surface (e.g., a board), it will only hold barely about 20%-30% of its nominal power. Gravity as well as a low friction coefficient influence the fact that magnets move down faster than they pull off. Want to create a wall mount? Remember that the shear force is much weaker than the maximum static pull force. On a slippery surface, the holder will give way down under a much lighter weight. Application of an anti-slip coating can drastically raise the stability.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 70x50 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	3%	5.61 kg / 12.36 lbs 5607.0 g / 55.0 N

2 mm	17%	28.03 kg / 61.81 lbs 28035.0 g / 275.0 N
3 mm	25%	42.05 kg / 92.71 lbs 42052.5 g / 412.5 N
5 mm	42%	70.09 kg / 154.52 lbs 70087.5 g / 687.6 N
10 mm	83%	140.18 kg / 309.03 lbs 140175.0 g / 1375.1 N
11 mm	92%	154.19 kg / 339.94 lbs 154192.5 g / 1512.6 N
12 mm	100%	168.21 kg / 370.84 lbs 168210.0 g / 1650.1 N

A thin sheet is not enough to conduct the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's power, you require a sufficiently solid backing of metal. The saturation effect causes that on thin elements (e.g., car bodies), the magnet holds weaker. We advise picking the steel cross-section from these parameters.

100 °C	-28.8%	119.77 kg / 264.04 lbs 119765.5 g / 1174.9 N

Ordinary NdFeB products change their properties power past the thermal threshold. Watch out for overheating – high temperature can irreversibly destroy this product. With every degree above norm, the neodymium's power briefly drops. Refrain from using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than long magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a larger range of operation. Designing a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is massive. The levitation is slightly lower than the attraction, but still significant.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Figures refer to friction force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Hazards (electronics) - warnings
MW 70x50 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	40.0 cm
Hearing aid	10 Gs (1.0 mT)	31.5 cm
Timepiece	20 Gs (2.0 mT)	24.5 cm
Mobile device	40 Gs (4.0 mT)	19.0 cm
Remote	50 Gs (5.0 mT)	17.5 cm
Payment card	400 Gs (40.0 mT)	7.5 cm
HDD hard drive	600 Gs (60.0 mT)	6.0 cm

Extremely neodym field is a serious hazard to electronic devices as well as pacemakers. These magnets generate a flux that destroys function of sensitive medical devices. Be aware: the unseen radiation acts through matter and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 70x50 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	13.97 km/h (3.88 m/s)	10.87 J
30 mm	20.06 km/h (5.57 m/s)	22.40 J
50 mm	24.70 km/h (6.86 m/s)	33.96 J
100 mm	34.46 km/h (9.57 m/s)	66.12 J

Magnetic elements are delicate – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Kinetic force can cause material chips or painful pinches to skin. Always hold the magnet during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when working with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Warning: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely limits the holding force.

3. Thermal stability

*For N38 grade, the safety limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.74

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

The presented product is an extremely powerful cylinder magnet, composed of durable NdFeB material, which, with dimensions of Ø70x50 mm, guarantees the highest energy density. The MW 70x50 / N38 component features high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 168.21 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 1650.14 N with a weight of only 1443.17 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø70x50), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø70x50 mm, which, at a weight of 1443.17 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 168.21 kg (force ~1650.14 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 70 mm. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Apart from their notable magnetism, neodymium magnets have these key benefits:

They retain attractive force for around 10 years – the drop is just ~1% (based on simulations),
Neodymium magnets remain highly resistant to magnetic field loss caused by external magnetic fields,
Thanks to the shiny finish, the surface of nickel, gold, or silver gives an elegant appearance,
Magnetic induction on the surface of the magnet remains extremely intense,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Considering the possibility of precise shaping and customization to individualized needs, neodymium magnets can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
Fundamental importance in innovative solutions – they find application in HDD drives, electromotive mechanisms, medical devices, as well as multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices

Disadvantages

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We recommend cover - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Detachment force of the magnet in optimal conditions – what affects it?

The declared magnet strength refers to the maximum value, recorded under ideal test conditions, meaning:

on a plate made of mild steel, optimally conducting the magnetic field
whose transverse dimension equals approx. 10 mm
with a surface cleaned and smooth
without any air gap between the magnet and steel
under axial application of breakaway force (90-degree angle)
in stable room temperature

Practical aspects of lifting capacity – factors

Real force is influenced by specific conditions, including (from priority):

Gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or dirt).
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Warnings

Pacemakers

Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Protective goggles

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets leads to them breaking into shards.

Electronic devices

Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).

Combustion hazard

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Threat to navigation

Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Allergy Warning

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands or select encased magnets.

Product not for children

Adult use only. Small elements pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.

Bone fractures

Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.

Immense force

Handle with care. Neodymium magnets act from a distance and snap with huge force, often quicker than you can react.

Permanent damage

Control the heat. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.
