Pulling power drops significantly with every mm of distance. Note that even the smallest gap (e.g., dirt, paint, rust) strongly diminishes the holding power. Magnetic products operate strongest in perfect adhesion; distance drastically cuts the power. Notice how quickly the pull force fall, when the product does not adhere flatly to the metal substrate. When calculating the mounting, avoid unnecessary gaps.

This section shows the theoretical force necessary to initiate the slippage of the magnet vertically along a upright metal surface (assuming typical friction). This parameter is relative to the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MPL 20x5x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.04 kg / 2.29 pounds 1038.0 g / 10.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.69 kg / 1.53 pounds 692.0 g / 6.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.35 kg / 0.76 pounds 346.0 g / 3.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.73 kg / 3.81 pounds 1730.0 g / 17.0 N

When mounting a element on a upright surface (e.g., a car body), it will maintain only approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient influence the fact that holders move down faster than they pull off. Planning a hanger? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a significantly smaller load. Utilizing a rubberized layer can drastically increase the grip.

A too thin steel is incapable of focus the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To achieve 100% of this neodymium's potential, you require a sufficiently solid piece of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the product holds weaker. We recommend selecting the steel thickness according to the table below.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Protect against heat – heat can permanently damage this product. With every degree above norm, the neodymium's force momentarily decreases. Do not use this product near heat sources exceeding its working range. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures than long magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and sheet setup. Such a system of two magnets creates a more powerful interaction and a wider radius of operation. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the pinch force is massive. The levitation is marginally weaker than the connection force, but still large.
*Flux density between like poles drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Note: Calculations apply to shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to electronics as well as medical implants. These neodymiums generate a field that disrupts operation of digital equipment. Remember: the unseen radiation acts through matter and plastic. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can cause material chips or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Shear force

*Caution: On a vertical wall, the magnet holds merely ~20% of its max power.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Power loss vs temp

*For standard magnets, 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) = 0.36

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 plate magnet made of NdFeB material, which, with dimensions of 20x5x3 mm and a weight of 2.25 g, guarantees the highest quality connection. This rectangular block with a force of 33.96 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.

The key to success is shifting 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 20x5x3 / 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 20x5x3 / 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. 3.46 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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. In practice, this means that this magnet has the greatest attraction force on its main planes (20x5 mm), which is ideal for flat mounting. 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: 20 mm (length), 5 mm (width), and 3 mm (thickness). It is a magnetic block with dimensions 20x5x3 mm and a self-weight of 2.25 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Apart from their notable magnetic energy, neodymium magnets have these key benefits:

Their magnetic field is durable, and after approximately ten years it decreases only by ~1% (theoretically),
They possess excellent resistance to weakening of magnetic properties when exposed to external fields,
By covering with a lustrous coating of nickel, the element acquires an aesthetic look,
Magnets are characterized by extremely high magnetic induction on the surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
In view of the ability of flexible shaping and customization to specialized requirements, NdFeB magnets can be manufactured in a wide range of geometric configurations, which makes them more universal,
Universal use in advanced technology sectors – they find application in mass storage devices, drive modules, medical equipment, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions

Cons

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Due to limitations in realizing nuts and complicated shapes in magnets, we propose using casing - magnetic holder.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

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

The declared magnet strength refers to the limit force, obtained under optimal environment, specifically:

on a base made of structural steel, perfectly concentrating the magnetic flux
possessing a thickness of minimum 10 mm to ensure full flux closure
characterized by lack of roughness
under conditions of gap-free contact (metal-to-metal)
during detachment in a direction perpendicular to the mounting surface
at room temperature

Practical aspects of lifting capacity – factors

Bear in mind that the working load may be lower influenced by the following factors, starting with the most relevant:

Clearance – existence of foreign body (paint, tape, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Material composition – not every steel attracts identically. Alloy additives weaken the attraction effect.
Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Conscious usage

Be careful. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.

Protect data

Equipment safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).

ICD Warning

For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to handle the magnets.

Combustion hazard

Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Heat warning

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

Product not for children

Only for adults. Tiny parts can be swallowed, leading to severe trauma. Keep away from children and animals.

Bodily injuries

Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Protective goggles

Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Precision electronics

Note: rare earth magnets generate a field that confuses sensitive sensors. Keep a safe distance from your mobile, tablet, and GPS.

Skin irritation risks

Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands or select versions in plastic housing.
