Pulling power drops significantly with every subsequent millimeter of spacing. Note that even a microscopic distance (e.g., contamination, varnish, dust) significantly diminishes the holding power. Neodymiums work most effectively at the point of direct contact; distance drastically cuts the force. Analyze how quickly the pull force plummet, when the magnet does not touch directly to the metal substrate. When planning the arrangement, discard unnecessary gaps.

The following data shows the theoretical holding capacity necessary to initiate the slippage of the magnet vertically against a vertical steel wall (considering typical friction coefficient). The holding force is relative to the distance between the magnet and the surface.

When placing a holder on a upright surface (e.g., a board), it will only hold only approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip influence the fact that products move down faster than they pull off. Planning a hanger? Note that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the element will slide down under a much lighter load. Using a rubber layer can significantly improve the result.

A too thin steel cannot focus the entire magnetic field, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid piece of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the product shows lower pull force. We recommend selecting the steel thickness based on the following data.

Standard neodymium magnets lose parameters above the temperature limit. Protect against heat – high temperature can permanently destroy this magnet. As the temperature rises, the magnet's power temporarily lowers. Refrain from using this product close to ovens exceeding its working range. Ignoring the limit will lead to destruction of magnetism.

*Engineering note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat 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 particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the pinch force is massive. The repulsion force is marginally weaker than the attraction, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Estimates apply to sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to IT equipment as well as pacemakers. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Increased vigilance must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Kinetic force can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds merely ~20% of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. computer case) severely weakens 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) = 0.14

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 an extremely strong plate magnet made of NdFeB material, which, with dimensions of 50x30x4 mm and a weight of 45 g, guarantees premium class connection. As a block magnet with high power (approx. 7.57 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is sliding 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. Watch your fingers! Magnets with a force of 7.57 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 50x30x4 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 7.57 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. 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).

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 (50x30 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 50x30x4 mm, which, at a weight of 45 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 7.57 kg (force ~74.26 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of neodymium magnets.

Pros

Apart from their strong power, neodymium magnets have these key benefits:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
Neodymium magnets are characterized by extremely resistant to demagnetization caused by external field sources,
A magnet with a metallic nickel surface looks better,
Magnetic induction on the working part of the magnet turns out to be maximum,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Thanks to freedom in designing and the ability to adapt to specific needs,
Huge importance in high-tech industry – they are commonly used in data components, electric drive systems, precision medical tools, as well as complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their power 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 stability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited possibility of creating nuts in the magnet and complicated forms - preferred is casing - mounting mechanism.
Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can complicate diagnosis medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding force – what contributes to it?

The declared magnet strength concerns the peak performance, measured under laboratory conditions, namely:

on a plate made of structural steel, perfectly concentrating the magnetic field
whose transverse dimension reaches at least 10 mm
with a surface cleaned and smooth
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (pull-off, not shear)
in temp. approx. 20°C

Practical lifting capacity: influencing factors

It is worth knowing that the application force will differ depending on elements below, in order of importance:

Air gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Angle of force application – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be lost into the air.
Plate material – low-carbon steel attracts best. Alloy steels reduce magnetic properties and lifting capacity.
Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets

Threat to navigation

GPS units and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Mechanical processing

Powder produced during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Protective goggles

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets will cause them cracking into shards.

Hand protection

Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!

Do not underestimate power

Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Nickel coating and allergies

Some people have a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. We suggest wear safety gloves.

Threat to electronics

Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and erase data from cards.

Medical interference

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Thermal limits

Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Adults only

Neodymium magnets are not suitable for play. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
