Magnetic force drops drastically with every subsequent millimeter of distance. Remember that even the smallest gap (e.g., contamination, varnish, rust) strongly diminishes the holding power. Magnetic products operate most effectively in perfect adhesion; air break weakens the force. Analyze how rapidly the pull force plummet, when the magnet does not adhere tightly to the steel surface. When designing the mounting, eliminate additional spacers.

Table 2: Slippage load (vertical surface)
MPL 7x7x3 / N38

Distance (mm)	Friction coefficient	Pull Force (kg/lbs/g/N)
0 mm	Stal (~0.2)	0.32 kg / 0.71 pounds 320.0 g / 3.1 N

50 mm	Stal (~0.2)	0.00 kg / 0.00 pounds 0.0 g / 0.0 N

The following data shows the estimated force sufficient to initiate the slippage of the magnet vertically along a upright metal surface (assuming typical friction coefficient). The holding force depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MPL 7x7x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.48 kg / 1.06 pounds 480.0 g / 4.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.32 kg / 0.71 pounds 320.0 g / 3.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.16 kg / 0.35 pounds 160.0 g / 1.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.80 kg / 1.76 pounds 800.0 g / 7.8 N

When placing a magnet on a upright surface (e.g., a fridge), it will maintain just approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that magnets move down easier than they pull off. Want to create a wall mount? Consider that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the holder will slip down under a noticeably lighter load. Utilizing a rubberized pad can significantly improve the result.

12 mm	100%	1.60 kg / 3.53 pounds 1600.0 g / 15.7 N

A thin sheet cannot focus the entire magnetic field, which weakens actual performance of the magnet. If you install a neodymium to a thin surface, the field will pass right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's power, you need a suitably thick backing of steel. The material oversaturation causes that on thin elements (e.g., appliance housings), the magnet works worse. We recommend selecting the steel thickness according to the table below.

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Watch out for overheating – heat can permanently destroy this magnet. With increasing heat, the magnet's capacity momentarily lowers. Do not use this product close to heaters exceeding its working range. Ignoring the limit will result in permanent loss of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) risk losing magnetic properties sooner than long magnets. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a much further distance than a magnet and steel setup. Such a system of magnet-to-magnet generates a stronger field and a further horizon of operation. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the impact force is extreme. The levitation is a bit weaker than the attraction, but still large.
*The magnetic induction for N-N configuration reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
* Calculations apply to friction force of a pair of same magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to IT equipment and medical implants. These NdFeB products produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation penetrates the body and plastic. Exceptional care must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can cause material chips or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

Water (riverbed)	1.83 kg (+0.23 kg buoyancy gain)	+14.5%

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. 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 holds only approx. 20-30% of its nominal pull.

2. Plate thickness effect

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.48

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 7x7x3 mm and a weight of 1.1 g, guarantees premium class connection. This magnetic block with a force of 15.70 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat 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 1.60 kg can pinch very hard and cause hematomas. 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 invisible mounts 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 7x7x3 / N38, it is best to use strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 7x7x3 / N38 model is magnetized through the thickness (dimension 3 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 (7x7 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 7x7x3 mm, which, at a weight of 1.1 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 1.60 kg (force ~15.70 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They retain magnetic properties for nearly 10 years – the loss is just ~1% (in theory),
Neodymium magnets are characterized by extremely resistant to demagnetization caused by external magnetic fields,
By applying a lustrous coating of gold, the element presents an nice look,
Magnets possess huge magnetic induction on the working surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to versatility in designing and the ability to modify to unusual requirements,
Fundamental importance in electronics industry – they serve a role in mass storage devices, electric drive systems, medical devices, and complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. 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 magnets in rubber or plastics, which prevent oxidation and corrosion.
Limited possibility of making nuts in the magnet and complex shapes - preferred is cover - mounting mechanism.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can be problematic in diagnostics medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

The declared magnet strength concerns the maximum value, measured under laboratory conditions, specifically:

on a plate made of mild steel, effectively closing the magnetic field
whose transverse dimension is min. 10 mm
with a plane perfectly flat
without any air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
in stable room temperature

Lifting capacity in real conditions – factors

During everyday use, the real power results from several key aspects, ranked from the most important:

Distance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be lost to the other side.
Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate lowers the holding force.

Warnings

Electronic hazard

Data protection: Strong magnets can ruin data carriers and sensitive devices (heart implants, medical aids, mechanical watches).

Do not underestimate power

Exercise caution. Rare earth magnets act from a long distance and connect with huge force, often faster than you can move away.

Warning for allergy sufferers

It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or choose coated magnets.

Combustion hazard

Machining of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Do not give to children

Always store magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are very dangerous.

Threat to navigation

Be aware: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your phone, tablet, and navigation systems.

Heat warning

Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Danger to pacemakers

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Magnet fragility

Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.

Serious injuries

Protect your hands. Two powerful magnets will join immediately with a force of massive weight, crushing everything in their path. Be careful!
