Grip strength drops drastically per each millimeter of spacing. Note that even the smallest gap (e.g., dirt, paint, veneer) noticeably reduces the pull force. Neodymiums work most effectively during direct contact; distance weakens the force. See how flashily the pull force plummet, when the magnet does not touch tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

The following data presents the approximate shear load necessary to cause the downward movement of the magnet vertically against a vertical steel wall (considering standard friction). This parameter varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
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
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 0.71 LBS 320.0 g / 3.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.60 kg / 3.53 LBS 1600.0 g / 15.7 N

When placing a element on a upright wall (e.g., a car body), it will maintain only approx. 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient mean that products slip faster than they pop off the substrate. Planning a vertical fastening? Note that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter load. Utilizing a rubberized pad can significantly improve the result.

A too thin steel is incapable of conduct the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a thin surface, the magnetism will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid element of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the product works worse. We advise picking the steel dimension according to the table below.

Classic neodymiums change their properties power past the thermal threshold. Watch out for overheating – excessive heat can irreversibly destroy this product. As the temperature rises, the neodymium's capacity briefly drops. Do not use this product near heat sources exceeding its working range. Exceeding the critical threshold will lead to irreversible degradation of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and sheet combination. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Designing a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the impact force is massive. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Figures apply to sliding force of two identical magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to IT equipment as well as medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field passes through tissues and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the magnet. Wear eye protection when playing with powerful specimens.

Rust risk: 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. Wall mount (shear)

*Note: On a vertical wall, the magnet holds just approx. 20-30% of its max power.

2. Steel thickness impact

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

3. Power loss vs temp

*For N38 grade, the critical limit is 80°C.

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

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

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. As a block magnet with high power (approx. 3.20 kg), this product is available immediately 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 15x5x5 / 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. 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. They work great as invisible mounts under tiles, wood, or glass. 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.

Standardly, the MPL 15x5x5 / N38 model is magnetized axially (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. 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.

This model is characterized by dimensions 15x5x5 mm, which, at a weight of 2.81 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 3.20 kg (force ~31.38 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of rare earth magnets.

Pros

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

They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
They show high resistance to demagnetization induced by external disturbances,
A magnet with a metallic silver surface looks better,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Due to the ability of free forming and adaptation to individualized solutions, NdFeB magnets can be modeled in a wide range of geometric configurations, which expands the range of possible applications,
Huge importance in modern technologies – they are used in data components, electric motors, advanced medical instruments, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Disadvantages

Problematic aspects of neodymium magnets: tips and applications.

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
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 stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of producing nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

The specified lifting capacity refers to the limit force, obtained under optimal environment, specifically:

using a plate made of low-carbon steel, serving as a magnetic yoke
possessing a thickness of min. 10 mm to avoid saturation
with an polished contact surface
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
in neutral thermal conditions

Determinants of practical lifting force of a magnet

Real force is affected by specific conditions, including (from most important):

Air gap (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be lost into the air.
Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

Precautions when working with NdFeB magnets

Respect the power

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

No play value

NdFeB magnets are not intended for children. Accidental ingestion of a few magnets may result in them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them breaking into small pieces.

Data carriers

Intense magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Heat warning

Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and strength.

Physical harm

Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.

Medical interference

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Keep away from electronics

A strong magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.

Flammability

Dust generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.

Nickel coating and allergies

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
