Grip strength weakens significantly per each millimeter of distance. Note that even the smallest gap (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Magnetic products operate optimally in perfect adhesion; gap weakens the force. Observe how flashily the parameters plummet, when the magnet does not adhere flatly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

The following data defines the approximate shear load sufficient to cause the downward movement of the magnet down on a upright steel wall (assuming standard friction coefficient). This parameter varies with the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull

When hanging a element on a vertical wall (e.g., a board), it will only hold only about 1/5 of its maximum pull force. Gravitational force as well as a low friction coefficient influence the fact that magnets move down faster than they detach. Planning a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slip down under a significantly smaller load. Application of an anti-slip pad can drastically increase the grip.

A thin sheet is incapable of conduct the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you need a suitably thick backing of metal. The saturation phenomenon means that on delicate walls (e.g., appliance housings), the product shows lower pull force. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – heat can permanently demagnetize this magnet. As the temperature rises, the neodymium's force briefly decreases. Avoid using this product in hot environments exceeding its safe range. Ignoring the limit will lead to permanent loss of magnetism.

*Important note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Estimates refer to shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Magnetic elements are delicate – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A collision at high speed means shattering of the neodymium. Wear eye protection 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.

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical surface, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.43

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 plate magnet made of NdFeB material, which, with dimensions of 40x18x10 mm and a weight of 54 g, guarantees premium class connection. This magnetic block with a force of 233.58 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 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 40x18x10 SH / 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.

They constitute a key element in the production of generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 40x18x10 SH / N38, we recommend utilizing 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. 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: 40 mm (length), 18 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 40x18x10 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 and cons of Nd₂Fe₁₄B magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:

They do not lose magnetism, even over approximately 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
A magnet with a metallic nickel surface looks better,
They show 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...
Possibility of custom modeling and modifying to defined needs,
Significant place in high-tech industry – they are commonly used in data components, motor assemblies, advanced medical instruments, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems

Limitations

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in creating threads and complex forms in magnets, we recommend using casing - magnetic holder.
Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these devices can disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what contributes to it?

The lifting capacity listed is a result of laboratory testing conducted under the following configuration:

using a base made of low-carbon steel, acting as a ideal flux conductor
with a thickness minimum 10 mm
with a surface cleaned and smooth
with zero gap (without paint)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Determinants of lifting force in real conditions

In real-world applications, the actual holding force depends on many variables, ranked from most significant:

Clearance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Direction of force – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be escaped into the air.
Plate material – mild steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Warnings

Caution required

Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.

Eye protection

Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them shattering into small pieces.

Medical implants

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Keep away from computers

Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).

Keep away from children

NdFeB magnets are not toys. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.

Allergy Warning

Medical facts indicate that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands and choose coated magnets.

Physical harm

Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.

Demagnetization risk

Control the heat. Heating the magnet to high heat will destroy its properties and strength.

Fire warning

Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Threat to navigation

A powerful magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.

Warning! Details about risks in the article: Safety of working with magnets.
