Grip strength drops drastically per each millimeter of gap. Remember that even a microscopic distance (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnets hold most effectively during direct contact; distance nullifies the force. Notice how flashily the load capacity fall, when the magnet does not adhere directly to the steel surface. When planning the mounting, avoid redundant distances.

The following data calculates the estimated force required to start the sliding of the magnet vertically on a upright steel wall (assuming standard friction). This value is a function of the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 20x20x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.62 kg / 10.19 lbs 4620.0 g / 45.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.08 kg / 6.79 lbs 3080.0 g / 30.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.54 kg / 3.40 lbs 1540.0 g / 15.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	7.70 kg / 16.98 lbs 7700.0 g / 75.5 N

When mounting a holder on a vertical wall (e.g., a car body), it will maintain barely about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip mean that magnets move down easier than they pop off the substrate. Want to create a hanger? Note that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a much lighter weight. Application of an anti-slip pad can effectively improve the result.

A too thin steel is incapable of conduct the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a weak sheet, the field will pass right through and the holding will be smaller. To squeeze the maximum of this neodymium's potential, you need a suitably thick element of metal. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the product shows lower pull force. We suggest choosing the steel dimension from these parameters.

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly damage this magnet. As the temperature rises, the neodymium's force momentarily decreases. Do not use this product near heat sources exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) risk losing magnetic properties at lower temperatures than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Want to build a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when bringing together two magnets, the pinch force is massive. The repulsion force is slightly lower than the connection force, but still significant.
*The magnetic induction for N-N configuration drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Results refer to shear force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to electronics as well as pacemakers. These NdFeB products generate a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and housings. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when working with large magnets.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains merely approx. 20-30% of its max power.

2. Steel saturation

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

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.84

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 20x20x20 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 151.12 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.

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 20x20x20 / 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 generators and material handling systems. They work great as invisible mounts 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 20x20x20 / N38 model is magnetized axially (dimension 20 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 20x20x20 mm, which, at a weight of 60 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 20x20x20 mm and a self-weight of 60 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:

Their strength is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
In other words, due to the reflective finish of gold, the element gains a professional look,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of individual modeling as well as adapting to individual conditions,
Huge importance in future technologies – they are used in hard drives, electric drive systems, precision medical tools, and multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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 secure oxidation and corrosion.
Limited ability of making threads in the magnet and complex forms - preferred is cover - magnet mounting.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

Magnet power was defined for ideal contact conditions, including:

using a sheet made of mild steel, functioning as a circuit closing element
possessing a massiveness of minimum 10 mm to avoid saturation
characterized by smoothness
without the slightest insulating layer between the magnet and steel
during pulling in a direction perpendicular to the mounting surface
at temperature room level

What influences lifting capacity in practice

It is worth knowing that the magnet holding will differ subject to elements below, in order of importance:

Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be escaped to the other side.
Chemical composition of the base – mild steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.

Warnings

Risk of cracking

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

Metal Allergy

Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, prevent direct skin contact or choose coated magnets.

Choking Hazard

Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep away from children and animals.

Protect data

Do not bring magnets close to a purse, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Phone sensors

Be aware: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, device, and GPS.

Implant safety

Patients with a pacemaker must maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Finger safety

Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Machining danger

Dust created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Heat warning

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.

Safe operation

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