Magnetic force weakens sharply with every subsequent millimeter of gap. Note that even the smallest gap (e.g., contamination, paint, rust) strongly diminishes the holding power. Magnets hold optimally at the point of direct contact; air break nullifies the power. See how quickly the parameters drop, when the magnet does not touch directly to the metal substrate. When designing the arrangement, discard redundant distances.

The following data calculates the theoretical holding capacity required to initiate the sliding of the magnet vertically along a vertical steel wall (considering standard friction coefficient). The holding force varies with the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 3x3x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.11 kg / 0.24 pounds 108.0 g / 1.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.07 kg / 0.16 pounds 72.0 g / 0.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.08 pounds 36.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.18 kg / 0.40 pounds 180.0 g / 1.8 N

When hanging a holder on a vertical surface (e.g., a car body), it you can count on just about 20%-30% of its nominal power. Gravity and a weak degree of grip cause that holders slide down faster than they detach. Want to create a wall mount? Consider that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the holder will give way down under a much lighter load. Application of an anti-slip coating can drastically raise the stability.

12 mm	100%	0.36 kg / 0.79 pounds 360.0 g / 3.5 N

A thin metal plate is not enough to absorb the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's potential, you need a suitably thick piece of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the product holds weaker. We recommend selecting the steel cross-section based on the following data.

Standard neodymium magnets lose strength after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently destroy this magnet. With increasing heat, the neodymium's capacity temporarily lowers. Refrain from using this magnet close to ovens exceeding its working range. Ignoring the limit will lead to destruction of magnetism.

*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a magnet and steel combination. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. 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 collision energy is huge. The repulsion force is a bit weaker than the connection force, but still large.
*Flux density between like poles reaches ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Figures demonstrate friction force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronic devices and pacemakers. These magnets produce a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Neodymium magnets are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when handling with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains just a fraction of its perpendicular strength.

2. Steel saturation

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

3. Temperature resistance

*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) = 0.66

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.

Model MPL 3x3x2 / N38 features a low profile and professional pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 0.36 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is sliding 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 3x3x2 / 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.

Plate magnets MPL 3x3x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 0.36 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.

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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 3 mm (length), 3 mm (width), and 2 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 0.36 kg (force ~3.49 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 rare earth magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They have stable power, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by external magnetic fields,
A magnet with a shiny gold surface has better aesthetics,
The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of detailed machining as well as optimizing to precise conditions,
Universal use in future technologies – they are used in magnetic memories, brushless drives, advanced medical instruments, as well as multitasking production systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We suggest casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these products are able to complicate diagnosis medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what affects it?

The load parameter shown represents the maximum value, measured under ideal test conditions, namely:

on a plate made of mild steel, optimally conducting the magnetic flux
possessing a thickness of min. 10 mm to avoid saturation
with an ideally smooth touching surface
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
at standard ambient temperature

What influences lifting capacity in practice

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

Air gap (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or debris).
Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Metal 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.
Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the load capacity.

H&S for magnets

Life threat

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Electronic devices

Device Safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).

Conscious usage

Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Phone sensors

Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and navigation systems.

Serious injuries

Protect your hands. Two large magnets will join immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Allergic reactions

Studies show that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands or opt for encased magnets.

Flammability

Dust produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Shattering risk

Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Heat sensitivity

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.

Adults only

Strictly store magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are fatal.

Security! Learn more about risks in the article: Magnet Safety Guide.
