Magnetic force weakens sharply per each millimeter of gap. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) strongly diminishes the holding power. Neodymiums work optimally in perfect adhesion; gap weakens the power. Notice how rapidly the parameters drop, when the magnet does not adhere directly to the metal substrate. When designing the assembly, discard unnecessary gaps.

This section calculates the estimated force required to cause the shifting of the magnet vertically against a upright metal surface (considering typical friction coefficient). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 5x5x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.17 kg / 0.38 lbs 174.0 g / 1.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.12 kg / 0.26 lbs 116.0 g / 1.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.06 kg / 0.13 lbs 58.0 g / 0.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.29 kg / 0.64 lbs 290.0 g / 2.8 N

When mounting a element on a upright wall (e.g., a fridge), it will maintain barely approx. 1/5 of nominal attraction strength. Gravity and a weak degree of grip cause that magnets move down faster than they detach. Designing a wall mount? Consider that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the element will slide down under a significantly smaller load. Using a rubber pad can drastically raise the stability.

12 mm	100%	0.58 kg / 1.28 lbs 580.0 g / 5.7 N

A too thin steel is not enough to take in the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the magnetism will pass right through and the holding will be smaller. To squeeze 100% of this neodymium's potential, you require a sufficiently solid piece of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets lose power past the thermal threshold. Watch out for overheating – high temperature can permanently destroy this magnet. As the temperature rises, the neodymium's force briefly decreases. Do not use this magnet in hot environments exceeding its working range. Too high temperature will result in irreversible degradation of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnets interact from a much further distance than a neodymium and metal setup. The setup of two magnets produces a massive flux and a wider radius of action. Want to build a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still impressive.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
* Figures demonstrate shear force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Protective zones (electronics) - warnings

Powerful magnet radiation poses a serious hazard to electronics and pacemakers. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation acts through matter and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - warning
MPL 5x5x1.5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	45.91 km/h (12.75 m/s)	0.02 J
30 mm	79.50 km/h (22.08 m/s)	0.07 J
50 mm	102.64 km/h (28.51 m/s)	0.11 J
100 mm	145.15 km/h (40.32 m/s)	0.23 J

NdFeB products are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Impact energy can cause material chips or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when working with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. 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 holds only a fraction of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.36

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 5x5x1.5 mm and a weight of 0.28 g, guarantees premium class connection. This magnetic block with a force of 5.68 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. To separate the MPL 5x5x1.5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, 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 wind generators and material handling systems. Thanks to the flat surface and high force (approx. 0.58 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 5x5x1.5 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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 roughen and wash 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. In practice, this means that this magnet has the greatest attraction force on its main planes (5x5 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 5x5x1.5 mm, which, at a weight of 0.28 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 0.58 kg (force ~5.68 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of neodymium magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose power, even over around ten years – the drop in strength is only ~1% (based on measurements),
They are extremely resistant to demagnetization induced by presence of other magnetic fields,
The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to look better,
Magnets are characterized by huge magnetic induction on the active area,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of accurate forming and adjusting to defined needs,
Universal use in high-tech industry – they find application in mass storage devices, electromotive mechanisms, medical equipment, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices

Weaknesses

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
Limited possibility of creating threads in the magnet and complicated shapes - preferred is casing - magnet mounting.
Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these magnets can complicate diagnosis medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

The load parameter shown represents the peak performance, measured under ideal test conditions, namely:

on a block made of mild steel, optimally conducting the magnetic flux
possessing a massiveness of min. 10 mm to avoid saturation
characterized by even structure
under conditions of ideal adhesion (metal-to-metal)
during detachment in a direction vertical to the mounting surface
in stable room temperature

Lifting capacity in practice – influencing factors

Bear in mind that the magnet holding will differ influenced by the following factors, starting with the most relevant:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with neodymium magnets

Compass and GPS

Note: neodymium magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and GPS.

Data carriers

Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Danger to pacemakers

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Respect the power

Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.

Maximum temperature

Keep cool. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Mechanical processing

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

Nickel coating and allergies

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact and choose encased magnets.

Keep away from children

Strictly store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are life-threatening.

Crushing force

Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!

Material brittleness

Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
