Grip strength drops drastically with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) significantly weakens the grip. Neodymiums work optimally in perfect adhesion; distance drastically cuts the power. See how flashily the load capacity drop, when the product does not adhere directly to the metal substrate. When calculating the mounting, eliminate unnecessary gaps.

This section calculates the approximate weight limit required to cause the slippage of the magnet vertically on a vertical metal surface (assuming standard friction). This value is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 40x10x18 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	5.02 kg / 11.06 lbs 5016.0 g / 49.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.34 kg / 7.37 lbs 3344.0 g / 32.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.67 kg / 3.69 lbs 1672.0 g / 16.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	8.36 kg / 18.43 lbs 8360.0 g / 82.0 N

When mounting a magnet on a vertical plane (e.g., a board), it will maintain just approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip influence the fact that holders slip easier than they pop off the substrate. Planning a wall mount? Remember that the shear force is significantly lower than the maximum static pull force. On a painted metal, the holder will slip down under a much lighter load. Application of an anti-slip coating can effectively increase the grip.

A too thin steel is incapable of absorb the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the flux will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you require a sufficiently solid backing of steel. The material oversaturation means that on thin elements (e.g., car bodies), the product holds weaker. We suggest choosing the steel cross-section based on the following data.

Ordinary NdFeB products lose strength past the thermal threshold. Protect against heat – excessive heat can permanently destroy this magnet. As the temperature rises, the neodymium's capacity momentarily drops. Avoid using this product close to ovens exceeding its working range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the collision energy is huge. The levitation is slightly lower than the connection force, but still significant.
*Field value for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Attention: Figures refer to shear force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to electronic devices and pacemakers. These neodymiums produce a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation passes through tissues and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a collision with steel can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or painful pinches to skin. Be sure to control the product during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when handling with powerful specimens.

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

The magnetic field penetrates through water without any losses. 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 merely approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*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) = 0.79

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 magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x10x18 mm and a weight of 54 g, guarantees the highest quality connection. This magnetic block with a force of 164.01 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, 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 40x10x18 / 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.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 40x10x18 / N38, it is best to use strong epoxy glues (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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

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 40x10x18 mm, which, at a weight of 54 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 40x10x18 mm and a self-weight of 54 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 neodymium magnets.

Strengths

Besides their exceptional field intensity, neodymium magnets offer the following advantages:

They retain full power for nearly ten years – the drop is just ~1% (according to analyses),
They feature excellent resistance to weakening of magnetic properties due to external magnetic sources,
Thanks to the shiny finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to flexibility in forming and the capacity to modify to complex applications,
Wide application in electronics industry – they find application in data components, brushless drives, medical devices, also modern systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Cons

Problematic aspects of neodymium magnets and proposals for their use:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases 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 durability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of creating threads in the magnet and complicated forms - preferred is cover - mounting mechanism.
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 devices are able to complicate diagnosis medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

Information about lifting capacity was defined for ideal contact conditions, taking into account:

with the application of a yoke made of special test steel, ensuring full magnetic saturation
with a cross-section minimum 10 mm
with a surface free of scratches
without any clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
in neutral thermal conditions

Lifting capacity in real conditions – factors

In real-world applications, the actual holding force is determined by a number of factors, presented from most significant:

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.

H&S for magnets

Heat warning

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Magnetic interference

Note: neodymium magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and GPS.

Fire warning

Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Medical implants

Patients with a heart stimulator must keep an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.

Do not give to children

Always keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.

Handling rules

Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can react.

Serious injuries

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!

Eye protection

NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.

Nickel allergy

A percentage of the population experience a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Prolonged contact might lead to an allergic reaction. We recommend wear protective gloves.

Keep away from computers
