Engineering modeling of the magnet - data

The following values represent the direct effect of a engineering analysis. Values were calculated on models for the class Nd₂Fe₁₄B. Actual conditions might slightly deviate from the simulation results. Please consider these calculations as a supplementary guide for designers.

Grip strength drops sharply with every subsequent millimeter of spacing. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) noticeably reduces the pull force. Magnets hold most effectively during direct contact; air break weakens the power. Observe how rapidly the parameters drop, when the product does not adhere directly to the steel surface. When planning the arrangement, eliminate unnecessary gaps.

The following data shows the estimated holding capacity needed to initiate the shifting of the magnet vertically on a vertical metal surface (considering standard friction). This value is a function of the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 10x7x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.61 kg / 1.34 pounds 606.0 g / 5.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.40 kg / 0.89 pounds 404.0 g / 4.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.20 kg / 0.45 pounds 202.0 g / 2.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.01 kg / 2.23 pounds 1010.0 g / 9.9 N

When placing a magnet on a vertical plane (e.g., a board), it you can count on only about 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that holders slip easier than they pop off the substrate. Planning a wall mount? Note that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a significantly smaller cargo. Utilizing a rubberized layer can drastically improve the result.

A thin metal plate is unable to conduct the full magnetic flux, which wastes potential of the magnet. Should you install a neodymium to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's power, you require a sufficiently solid element of metal. The saturation phenomenon causes that on thin elements (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel dimension according to the table below.

Table 5: Thermal resistance (stability) - power drop

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Protect against heat – heat can irreversibly destroy this product. With increasing heat, the neodymium's power temporarily lowers. Refrain from using this product near heat sources exceeding its operating temperature limit. Too high temperature will result in irreversible degradation of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of operation. Designing a powerful holder? Use a pair of magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is massive. The repulsion force is slightly lower than the attraction, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs in the exact middle of the gap (resulting from vector opposition).
* Results demonstrate sliding force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - warnings

A strong magnetic field poses a large risk to electronics as well as pacemakers. These neodymiums generate a flux that destroys function of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - warning
MPL 10x7x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	36.15 km/h (10.04 m/s)	0.08 J

50 mm	80.63 km/h (22.40 m/s)	0.40 J
100 mm	114.03 km/h (31.68 m/s)	0.79 J

Magnetic elements are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when handling with large magnets.

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

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

2. Plate thickness effect

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Temperature resistance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.42

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 10x7x3 mm and a weight of 1.58 g, guarantees the highest quality connection. This magnetic block with a force of 19.82 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 10x7x3 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. They work great as fasteners under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 10x7x3 mm, which, at a weight of 1.58 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 2.02 kg (force ~19.82 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Apart from their consistent holding force, neodymium magnets have these key benefits:

They do not lose power, even after around 10 years – the reduction in lifting capacity is only ~1% (theoretically),
They are resistant to demagnetization induced by external magnetic fields,
In other words, due to the smooth surface of silver, the element becomes visually attractive,
They show high magnetic induction at the operating surface, which increases their power,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Thanks to freedom in shaping and the ability to adapt to complex applications,
Key role in modern technologies – they are used in HDD drives, motor assemblies, precision medical tools, also technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
We suggest a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Highest magnetic holding force – what contributes to it?

Information about lifting capacity was determined for optimal configuration, assuming:

using a base made of mild steel, serving as a circuit closing element
with a thickness no less than 10 mm
with an ideally smooth contact surface
under conditions of gap-free contact (metal-to-metal)
under vertical application of breakaway force (90-degree angle)
in stable room temperature

Key elements affecting lifting force

Effective lifting capacity is affected by working environment parameters, mainly (from most important):

Clearance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted into the air.
Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Eye protection

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Do not drill into magnets

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and wear gloves.

Operating temperature

Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Threat to electronics

Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Handling rules

Use magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and respect their power.

Pacemakers

For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Keep away from children

These products are not intended for children. Swallowing a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.

Pinching danger

Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!

GPS Danger

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Maintain magnets near a device to avoid damaging the sensors.
