Physical modeling of the magnet - technical parameters

The following information are the direct effect of a physical calculation. Values rely on models for the material Nd₂Fe₁₄B. Actual parameters may deviate from the simulation results. Use these data as a preliminary roadmap during assembly planning.

Grip strength drops sharply with every subsequent millimeter of spacing. Note that every additional insulation layer (e.g., dirt, varnish, dust) significantly reduces the pull force. Magnetic products work strongest during direct contact; gap nullifies the power. Analyze how quickly the pull force drop, when the product does not touch flatly to the metal substrate. When planning the mounting, eliminate additional spacers.

50 mm	Stal (~0.2)	0.01 kg / 0.02 LBS 8.0 g / 0.1 N

This section defines the estimated shear load needed to cause the sliding of the magnet down on a upright steel plate (considering standard friction coefficient). This value is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 45x25x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	8.54 kg / 18.84 LBS 8544.0 g / 83.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	5.70 kg / 12.56 LBS 5696.0 g / 55.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.85 kg / 6.28 LBS 2848.0 g / 27.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	14.24 kg / 31.39 LBS 14240.0 g / 139.7 N

When mounting a magnet on a vertical surface (e.g., a fridge), it will only hold only about 20%-30% of nominal attraction strength. Gravity and a low friction coefficient influence the fact that products slip faster than they pull off. Designing a hanger? Note that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the element will give way down under a much lighter weight. Utilizing a rubberized coating can drastically increase the grip.

A thin metal plate cannot take in the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a too thin substrate, the field will pass right through and the holding will be smaller. To squeeze the maximum of this magnet's potential, you need a suitably thick element of steel. The material oversaturation means that on thin elements (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Table 5: Thermal stability (material behavior) - resistance threshold

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

Standard neodymium magnets change their properties strength past the thermal threshold. Watch out for overheating – excessive heat can irreversibly destroy this product. With every degree above norm, the magnet's capacity briefly lowers. Refrain from using this product in hot environments higher than its operating temperature limit. Exceeding the critical threshold will result in permanent loss of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures than long magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel setup. The connection of two magnets produces a massive flux and a further horizon of operation. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is a bit weaker than the attraction, but still significant.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Results show sliding force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronics as well as pacemakers. These magnets produce a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and plastic. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can cause material chips or painful pinches to fingers. Hold the magnet firmly during mounting 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 playing with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains only a fraction of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely reduces the holding force.

3. Thermal stability

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.36

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 an extremely strong plate magnet made of NdFeB material, which, with dimensions of 45x25x10 mm and a weight of 84.38 g, guarantees the highest quality connection. As a block magnet with high power (approx. 28.48 kg), this product is available off-the-shelf from our warehouse in Poland. 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 45x25x10 / 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. 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 generators and material handling systems. Thanks to the flat surface and high force (approx. 28.48 kg), they are ideal as hidden locks 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 45x25x10 / N38, it is best to use two-component adhesives (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 45x25x10 / N38 model is magnetized axially (dimension 10 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.

The presented product is a neodymium magnet with precisely defined parameters: 45 mm (length), 25 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 45x25x10 mm and a self-weight of 84.38 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros and cons of Nd₂Fe₁₄B magnets.

Strengths

Besides their exceptional strength, neodymium magnets offer the following advantages:

They do not lose magnetism, even during nearly ten years – the drop in lifting capacity is only ~1% (theoretically),
They feature excellent resistance to magnetic field loss when exposed to external magnetic sources,
In other words, due to the aesthetic layer of gold, the element gains visual value,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
Possibility of individual forming as well as adapting to defined needs,
Huge importance in modern industrial fields – they are used in computer drives, electromotive mechanisms, medical devices, also multitasking production systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

Drawbacks and weaknesses of neodymium magnets: application proposals

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and 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
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these devices are able to disrupt the diagnostic process medical when they are in the body.
Due to expensive raw materials, their price is relatively high,

Pull force analysis

Maximum holding power of the magnet – what affects it?

The lifting capacity listed is a theoretical maximum value executed under the following configuration:

with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
with a thickness minimum 10 mm
characterized by lack of roughness
with zero gap (no paint)
for force acting at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

In real-world applications, the actual holding force depends on a number of factors, presented from most significant:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Chemical composition of the base – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Precautions when working with neodymium magnets

Compass and GPS

Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.

Powerful field

Be careful. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.

Adults only

Strictly store magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.

Allergic reactions

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, cease working with magnets and wear gloves.

Serious injuries

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!

Warning for heart patients

Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Operating temperature

Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.

Dust explosion hazard

Powder created during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Shattering risk

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them shattering into shards.

Safe distance

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