Magnetic force drops drastically with every mm of spacing. Remember that even a microscopic distance (e.g., contamination, paint, rust) significantly reduces the pull force. Magnets work most effectively in perfect adhesion; distance nullifies the power. Analyze how flashily the parameters drop, when the product does not touch directly to the steel surface. When planning the assembly, eliminate redundant distances.

When mounting a holder on a upright surface (e.g., a car body), it you can count on only about 1/5 of its maximum pull force. Gravity and a weak degree of grip influence the fact that products slide down faster than they pop off the substrate. Want to create a vertical fastening? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the holder will give way down under a noticeably lighter load. Utilizing a rubberized pad can effectively raise the stability.

A thin metal plate is incapable of take in the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze 100% of this magnet's power, you require a sufficiently solid backing of metal. The material oversaturation causes that on delicate walls (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel dimension from these parameters.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently demagnetize this product. With every degree above norm, the neodymium's force momentarily decreases. Avoid using this product close to heaters higher than its working range. Too high temperature will lead to permanent loss of magnetic properties.
*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. Red status in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet produces a massive flux and a wider radius of operation. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the impact force is huge. The levitation is marginally weaker than the attraction, but still large.
*Flux density between like poles reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Figures refer to shear force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a real danger to electronics and pacemakers. These magnets produce a field that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with large magnets.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains only a fraction of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.26

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 Pc (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 Pc 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 60x10x5 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 18.16 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.
Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 18.16 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
They constitute a key element in the production of wind generators and material handling systems. Thanks to the flat surface and high force (approx. 18.16 kg), they are ideal as closers in furniture making and mounting elements in automation. 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 60x10x5 / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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).
Standardly, the MPL 60x10x5 / N38 model is magnetized through the thickness (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (60x10 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: 60 mm (length), 10 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 60x10x5 mm and a self-weight of 22.5 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Benefits

Apart from their strong magnetism, neodymium magnets have these key benefits:
  • They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
  • They show high resistance to demagnetization induced by presence of other magnetic fields,
  • Thanks to the shimmering finish, the layer of nickel, gold, or silver gives an clean appearance,
  • They are known for high magnetic induction at the operating surface, which increases their power,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Considering the ability of accurate shaping and customization to individualized projects, magnetic components can be created in a variety of forms and dimensions, which expands the range of possible applications,
  • Wide application in advanced technology sectors – they are utilized in data components, brushless drives, precision medical tools, also technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems

Disadvantages

Cons of neodymium magnets: tips and applications.
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
  • We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
  • Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical after entering the body.
  • Due to neodymium price, their price is relatively high,

Pull force analysis

Maximum lifting force for a neodymium magnet – what it depends on?

The force parameter is a result of laboratory testing performed under the following configuration:
  • using a plate made of mild steel, functioning as a ideal flux conductor
  • with a thickness no less than 10 mm
  • with an polished touching surface
  • with direct contact (without impurities)
  • under vertical force vector (90-degree angle)
  • at room temperature

Magnet lifting force in use – key factors

Real force impacted by specific conditions, mainly (from most important):
  • Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of maximum force).
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel type – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
  • Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
  • Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the holding force.

Precautions when working with NdFeB magnets
Beware of splinters

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Thermal limits

Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Physical harm

Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.

Electronic hazard

Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).

Swallowing risk

Strictly store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are life-threatening.

Warning for heart patients

For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Safe operation

Be careful. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.

Phone sensors

Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.

Nickel coating and allergies

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.

Mechanical processing

Powder generated during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
