Magnetic force drops drastically with every subsequent millimeter of spacing. Keep in mind that every additional insulation layer (e.g., dirt, paint, veneer) significantly weakens the grip. Magnets work most effectively in perfect adhesion; gap drastically cuts the power. Analyze how quickly the parameters fall, when the magnet does not adhere flatly to the steel surface. When calculating the mounting, eliminate additional spacers.

This section shows the theoretical force needed to initiate the sliding of the magnet vertically against a vertical steel wall (assuming typical friction). This value is relative to the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 15x5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.96 kg / 2.12 lbs 960.0 g / 9.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 1.41 lbs 640.0 g / 6.3 N

When placing a holder on a vertical plane (e.g., a fridge), it will maintain just approx. 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip influence the fact that magnets slip easier than they pull off. Designing a hanger? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a significantly smaller cargo. Application of an anti-slip layer can significantly improve the result.

A thin metal plate is unable to conduct the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's power, you need a suitably thick backing of steel. The saturation effect means that on delicate walls (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel dimension based on the following data.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Avoid high temperatures – heat can permanently demagnetize this product. With every degree above norm, the magnet's force temporarily lowers. Refrain from using this product near heat sources higher than its working range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a much further distance than a magnet and sheet combination. The connection of two magnets generates a stronger field and a wider radius of action. Want to build a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is a bit weaker than the attraction, but still large.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Results show sliding force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field is a serious hazard to electronics as well as pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation passes through tissues and glass. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can cause material chips or painful pinches to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Wear safety glasses when playing with large magnets.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains only a fraction of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) significantly weakens the holding force.

3. Heat tolerance

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.60

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 15x5x5 mm and a weight of 2.81 g, guarantees the highest quality connection. This rectangular block with a force of 31.38 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects 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 15x5x5 / 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. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 15x5x5 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 3.20 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

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.

The presented product is a neodymium magnet with precisely defined parameters: 15 mm (length), 5 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 15x5x5 mm and a self-weight of 2.81 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of rare earth magnets.

Advantages

Apart from their strong power, neodymium magnets have these key benefits:

They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
They feature excellent resistance to magnetism drop as a result of opposing magnetic fields,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to look better,
The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Considering the possibility of precise forming and adaptation to custom requirements, neodymium magnets can be created in a variety of shapes and sizes, which amplifies use scope,
Huge importance in advanced technology sectors – they are used in mass storage devices, drive modules, medical devices, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

What to avoid - cons of neodymium magnets: tips and applications.

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing threads and complicated forms in magnets, we recommend using cover - magnetic mount.
Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical when they are in the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

The declared magnet strength refers to the limit force, obtained under laboratory conditions, meaning:

with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
with a cross-section minimum 10 mm
with a surface perfectly flat
without the slightest insulating layer between the magnet and steel
under perpendicular application of breakaway force (90-degree angle)
in neutral thermal conditions

Magnet lifting force in use – key factors

Holding efficiency is affected by specific conditions, including (from priority):

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Load vector – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the load capacity.

H&S for magnets

Dust is flammable

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Eye protection

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Avoid contact if allergic

It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, prevent direct skin contact or select versions in plastic housing.

Cards and drives

Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Handling rules

Handle with care. Rare earth magnets act from a distance and snap with massive power, often faster than you can react.

Impact on smartphones

GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Adults only

Always keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.

Operating temperature

Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.

Implant safety

Individuals with a pacemaker must keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.

Crushing force

Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
