Physical simulation of the magnet - report

The following values are the outcome of a engineering analysis. Results are based on models for the class Nd₂Fe₁₄B. Actual conditions may differ. Use these calculations as a preliminary roadmap when designing systems.

50 mm	24 Gs 2.4 mT	0.00 kg / 0.00 pounds 0.6 g / 0.0 N	weak grip

Magnetic force drops significantly with every mm of gap. Note that even a very thin break (e.g., dirt, paint, dust) strongly weakens the grip. Neodymiums hold most effectively at the point of direct contact; gap nullifies the power. Notice how flashily the load capacity drop, when the magnet does not touch flatly to the metal substrate. When designing the assembly, eliminate redundant distances.

This section indicates the approximate force needed to start the downward movement of the magnet vertically against a upright metal surface (considering typical friction). This value is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 40x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.55 kg / 7.84 pounds 3555.0 g / 34.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.37 kg / 5.22 pounds 2370.0 g / 23.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.19 kg / 2.61 pounds 1185.0 g / 11.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.93 kg / 13.06 pounds 5925.0 g / 58.1 N

When mounting a magnet on a vertical wall (e.g., a fridge), it will maintain barely approx. 1/5 of its nominal power. Gravitational force as well as a weak degree of grip cause that holders move down easier than they pop off the substrate. Want to create a wall mount? Consider that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the holder will give way down under a significantly smaller weight. Application of an anti-slip layer can effectively raise the stability.

A thin metal plate cannot take in the entire magnetic field, which squanders power of the magnet. Should you install a neodymium to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's potential, you require a sufficiently solid element of metal. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the product shows lower pull force. We advise picking the steel dimension according to the table below.

Ordinary NdFeB products change their properties strength above the temperature limit. Watch out for overheating – excessive heat can permanently damage this magnet. With increasing heat, the magnet's power briefly decreases. Do not use this product close to ovens higher than its operating temperature limit. Ignoring the limit will lead to destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is massive. The levitation is slightly lower than the connection force, but still impressive.
*Field value in repulsion mode reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Attention: Results refer to friction force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to IT equipment and medical implants. These magnets produce a flux that disrupts operation of sensitive medical devices. Remember: the unseen radiation passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or painful pinches 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. Use safety goggles when playing with powerful specimens.

*Note: On a vertical wall, the magnet holds merely a fraction of its max power.

2. Steel thickness impact

*Thin steel (e.g. computer case) significantly reduces the holding force.

3. Power loss vs temp

*For N38 material, 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) = 0.31

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 40x10x5 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 116.27 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x10x5 / 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 wind generators and material handling systems. They work great as fasteners 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 40x10x5 / N38, it is best to use 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 40x10x5 / N38 model is magnetized axially (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 (40x10 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.

This model is characterized by dimensions 40x10x5 mm, which, at a weight of 15 g, makes it an element with high energy density. It is a magnetic block with dimensions 40x10x5 mm and a self-weight of 15 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros and cons of rare earth magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
They maintain their magnetic properties even under external field action,
Thanks to the smooth finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
They feature high magnetic induction at the operating surface, making them more effective,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to the ability of precise forming and customization to specialized requirements, magnetic components can be produced in a wide range of forms and dimensions, which amplifies use scope,
Universal use in high-tech industry – they are commonly used in computer drives, electric motors, precision medical tools, also industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its 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 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 recommend cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small elements of these devices are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

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

The load parameter shown concerns the limit force, obtained under laboratory conditions, meaning:

with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
possessing a massiveness of min. 10 mm to avoid saturation
characterized by smoothness
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

During everyday use, the actual holding force is determined by a number of factors, presented from crucial:

Air gap (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Steel thickness – too thin sheet causes magnetic saturation, causing part of the power to be wasted into the air.
Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.

Precautions when working with neodymium magnets

Demagnetization risk

Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.

Warning for allergy sufferers

Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact or choose versions in plastic housing.

Fire warning

Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Do not underestimate power

Handle with care. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can react.

Warning for heart patients

People with a pacemaker must maintain an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.

Keep away from electronics

Remember: neodymium magnets generate a field that confuses precision electronics. Keep a separation from your phone, device, and GPS.

Risk of cracking

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

Keep away from computers

Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Finger safety

Mind your fingers. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Product not for children

Neodymium magnets are not toys. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
