Grip strength decreases drastically with every subsequent millimeter of gap. Remember that every additional insulation layer (e.g., contamination, paint, rust) significantly diminishes the holding power. Magnetic products operate strongest during direct contact; gap nullifies the force. Notice how quickly the pull force drop, when the product does not adhere tightly to the metal substrate. When calculating the mounting, eliminate unnecessary gaps.

The following data calculates the theoretical force necessary to start the downward movement of the magnet downwards against a vertical steel plate (considering typical friction coefficient). This parameter depends on the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 11x11x1 / N38

Raw steel	µ = 0.3 30% Nominalnej Siły	0.13 kg / 0.28 LBS 129.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.19 LBS 86.0 g / 0.8 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.22 kg / 0.47 LBS 215.0 g / 2.1 N

When mounting a magnet on a upright surface (e.g., a car body), it will maintain barely approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient influence the fact that holders move down faster than they pop off the substrate. Want to create a hanger? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a significantly smaller cargo. Utilizing a rubberized coating can significantly improve the result.

A too thin steel is unable to conduct the entire magnetic field, which squanders power of the magnet. If you mount a strong magnet to a weak sheet, the flux will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's power, you require a sufficiently solid backing of steel. The saturation effect causes that on sheet metal structures (e.g., car bodies), the holder holds weaker. We recommend selecting the steel cross-section according to the table below.

Standard neodymium magnets change their properties power above the temperature limit. Watch out for overheating – excessive heat can permanently destroy this magnet. With every degree above norm, the neodymium's power momentarily decreases. Refrain from using this magnet close to heaters higher than its working range. Exceeding the critical threshold will cause permanent loss of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a much further distance than a neodymium and metal combination. Such a system of two magnets creates a more powerful interaction and a larger range of operation. Want to build a powerful holder? Apply two magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the pinch force is massive. The levitation is marginally weaker than the attraction, but still impressive.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
* Figures demonstrate shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronics and pacemakers. These magnets generate a flux that prevents correct functioning of digital equipment. Remember: the unseen radiation acts through matter and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains just a fraction of its nominal pull.

2. Plate thickness effect

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.13

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.

Component MPL 11x11x1 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 0.43 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 11x11x1 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, 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.

Plate magnets MPL 11x11x1 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. 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 11x11x1 / 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. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (11x11 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 11x11x1 mm, which, at a weight of 0.91 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 0.43 kg (force ~4.24 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:

Their power remains stable, and after around ten years it drops only by ~1% (according to research),
Neodymium magnets are characterized by highly resistant to magnetic field loss caused by magnetic disturbances,
The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets are distinguished by very high magnetic induction on the working surface,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Possibility of individual forming as well as optimizing to individual conditions,
Huge importance in electronics industry – they serve a role in hard drives, drive modules, diagnostic systems, as well as other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets: tips and applications.

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Limited ability of making threads in the magnet and complex forms - recommended is cover - magnetic holder.
Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices can complicate diagnosis medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

Breakaway force was defined for optimal configuration, taking into account:

on a base made of mild steel, optimally conducting the magnetic flux
with a cross-section no less than 10 mm
with a plane cleaned and smooth
with direct contact (no impurities)
for force applied at a right angle (pull-off, not shear)
in neutral thermal conditions

Determinants of practical lifting force of a magnet

Real force impacted by working environment parameters, mainly (from priority):

Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.

Warnings

Implant safety

People with a pacemaker must keep an large gap from magnets. The magnetic field can stop the functioning of the implant.

Product not for children

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

Bone fractures

Pinching hazard: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.

Magnetic media

Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Magnetic interference

A powerful magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.

Shattering risk

NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them cracking into shards.

Sensitization to coating

Some people have a contact allergy to Ni, which is the standard coating for neodymium magnets. Extended handling might lead to skin redness. We strongly advise wear protective gloves.

Heat sensitivity

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

Handling rules

Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.

Machining danger

Dust created during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
