Grip strength decreases drastically with every subsequent millimeter of gap. Remember that every additional insulation layer (e.g., dirt, varnish, rust) significantly diminishes the holding power. Magnetic products work strongest in perfect adhesion; air break kills the power. Observe how rapidly the pull force plummet, when the magnet does not touch flatly to the steel surface. When planning the mounting, avoid additional spacers.

The table below indicates the approximate holding capacity necessary to initiate the downward movement of the magnet down along a upright steel plate (assuming standard friction coefficient). This parameter varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - 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 magnet on a upright surface (e.g., a car body), it will only hold just approx. 20%-30% of nominal attraction strength. Gravity and a weak degree of grip influence the fact that holders slip faster than they pop off the substrate. Want to create a hanger? Note that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller load. Application of an anti-slip layer can significantly 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 unable to conduct the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a thin surface, the field will pass right through and the holding will be smaller. To achieve 100% of this neodymium's power, you need a suitably thick piece of metal. The saturation effect means that on delicate walls (e.g., appliance housings), the holder works worse. We recommend selecting the steel dimension based on the following data.

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

Classic neodymiums change their properties parameters past the thermal threshold. Protect against heat – excessive heat can permanently destroy this magnet. As the temperature rises, the neodymium's force briefly drops. Refrain from using this magnet in hot environments higher than its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Important note: Thermal stability is determined by both grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently at lower temperatures than long magnets. Red status in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a much further distance than a neodymium and metal setup. The setup of two magnets generates a stronger field and a further horizon of action. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the impact force is massive. The levitation is slightly lower than the attraction, but still large.
*The magnetic induction between like poles reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Attention: Results show shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronic devices and medical implants. These neodymiums generate a field that disrupts operation of sensitive medical devices. Notice: the unseen radiation penetrates the body and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning
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

NdFeB products are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or injury to skin. Always hold the magnet during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when playing with large magnets.

Environment	Effective steel pull	Effect
Air (land)	168.21 kg	Standard
Water (riverbed)	192.60 kg (+24.39 kg buoyancy gain)	+14.5%

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Warning: On a vertical surface, the magnet retains merely ~20% of its nominal pull.

2. Plate thickness effect

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

3. Heat tolerance

*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 offered product is an incredibly powerful cylindrical magnet, manufactured from advanced NdFeB material, which, at dimensions of Ø70x50 mm, guarantees maximum efficiency. This specific item features a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 168.21 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 1650.14 N with a weight of only 1443.17 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger 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 value of 1650.14 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1443.17 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 50 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 rare earth magnets.

Benefits

Besides their remarkable strength, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
They retain their magnetic properties even under close interference source,
In other words, due to the shiny surface of nickel, the element is aesthetically pleasing,
Magnets are characterized by very high magnetic induction on the surface,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Thanks to the ability of precise forming and adaptation to specialized needs, neodymium magnets can be produced in a variety of geometric configurations, which expands the range of possible applications,
Key role in innovative solutions – they serve a role in hard drives, electric drive systems, advanced medical instruments, and multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Disadvantages

Cons of neodymium magnets: tips and applications.

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products can disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum lifting capacity of the magnet – what contributes to it?

Holding force of 168.21 kg is a measurement result conducted under specific, ideal conditions:

using a sheet made of low-carbon steel, acting as a circuit closing element
with a cross-section no less than 10 mm
with a surface free of scratches
under conditions of ideal adhesion (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
in neutral thermal conditions

Lifting capacity in real conditions – factors

Holding efficiency is influenced by working environment parameters, such as (from most important):

Distance (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
Direction of force – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Hardened steels may attract less.
Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Heat – NdFeB sinters 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 testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safe handling of neodymium magnets

Threat to navigation

GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.

Shattering risk

Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Respect the power

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Metal Allergy

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease working with magnets and wear gloves.

Cards and drives

Do not bring magnets close to a wallet, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.

ICD Warning

Individuals with a pacemaker must keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.

Keep away from children

Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Store away from kids and pets.

Serious injuries

Pinching hazard: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.

Fire warning

Powder generated during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Demagnetization risk

Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
