Magnetic force decreases significantly with every subsequent millimeter of gap. Note that every additional insulation layer (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnetic products hold strongest in perfect adhesion; air break nullifies the force. Observe how flashily the parameters plummet, when the product does not adhere tightly to the steel surface. When calculating the arrangement, avoid unnecessary gaps.

This section indicates the theoretical holding capacity necessary to initiate the downward movement of the magnet down along a upright steel wall (assuming standard friction coefficient). This parameter is relative to the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 20x10x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.56 kg / 1.24 LBS 564.0 g / 5.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.83 LBS 376.0 g / 3.7 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.94 kg / 2.07 LBS 940.0 g / 9.2 N

When mounting a element on a upright wall (e.g., a fridge), it will only hold barely about 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient mean that holders move down faster than they detach. Want to create a vertical fastening? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will slip down under a significantly smaller load. Utilizing a rubberized coating can drastically increase the grip.

A too thin steel is incapable of conduct the entire magnetic field, which weakens actual performance of the holder. If you attach a powerful product to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To utilize full efficiency 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 magnet holds weaker. We recommend selecting the steel cross-section according to the table below.

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Protect against heat – heat can permanently damage this product. With every degree above norm, the magnet's capacity momentarily drops. Do not use this magnet close to ovens exceeding its operating temperature limit. Too high temperature will cause irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. Red status in the table signals permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a wider radius of operation. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the impact force is massive. The levitation is marginally weaker than the attraction, but still large.
*Flux density for N-N configuration is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Figures demonstrate shear force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to IT equipment and medical implants. These neodymiums produce a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Special caution must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can cause material chips or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when working with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Caution: On a vertical surface, the magnet retains merely ~20% of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

*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) = 0.19

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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.

Model MPL 20x10x2 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 1.88 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 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 20x10x2 / 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 20x10x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 20x10x2 / N38 model is magnetized axially (dimension 2 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. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 20x10x2 mm, which, at a weight of 3 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 20x10x2 mm and a self-weight of 3 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain attractive force for almost ten years – the loss is just ~1% (in theory),
They feature excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
By covering with a shiny coating of gold, the element acquires an aesthetic look,
Magnetic induction on the surface of the magnet turns out to be exceptional,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of detailed creating as well as modifying to individual conditions,
Huge importance in innovative solutions – they are utilized in data components, electromotive mechanisms, advanced medical instruments, as well as other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Cons of neodymium magnets: tips and applications.

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves 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 force. 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 while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing threads and complex forms in magnets, we recommend using cover - magnetic mechanism.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
Due to complex production process, their price is higher than average,

Lifting parameters

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

The specified lifting capacity represents the peak performance, recorded under optimal environment, specifically:

using a sheet made of mild steel, acting as a magnetic yoke
possessing a thickness of minimum 10 mm to ensure full flux closure
with an ideally smooth contact surface
under conditions of no distance (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

Real force is influenced by specific conditions, mainly (from most important):

Air gap (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Temperature – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Warning for heart patients

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Do not underestimate power

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Bodily injuries

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

Nickel coating and allergies

Studies show that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and select versions in plastic housing.

Protective goggles

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Threat to electronics

Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.

Choking Hazard

Always store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.

Precision electronics

GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Mechanical processing

Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.

Operating temperature

Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
