Grip strength weakens drastically with every subsequent millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, varnish, dust) strongly weakens the grip. Magnetic products operate optimally during direct contact; gap weakens the power. Notice how rapidly the load capacity drop, when the product does not adhere tightly to the steel surface. When calculating the mounting, discard redundant distances.

This section defines the approximate shear load required to start the sliding of the magnet vertically along a upright metal surface (considering standard friction). The holding force is a function of the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces

Raw steel	µ = 0.3 30% Nominalnej Siły	14.08 kg / 31.05 pounds 14082.0 g / 138.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	9.39 kg / 20.70 pounds 9388.0 g / 92.1 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	23.47 kg / 51.74 pounds 23470.0 g / 230.2 N

When mounting a magnet on a upright wall (e.g., a board), it will maintain just approx. 1/5 of its maximum pull force. Gravitational force as well as a low friction coefficient mean that magnets move down faster than they detach. Want to create a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller load. Utilizing a rubberized coating can drastically increase the grip.

A thin metal plate is incapable of conduct the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a thin surface, the flux will pass right through and the pull force will drop sharply. To utilize the maximum of this neodymium's potential, you require a sufficiently solid element of metal. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the magnet works worse. We suggest choosing the steel thickness based on the following data.

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly destroy this product. With increasing heat, the magnet's capacity temporarily drops. Avoid using this magnet close to heaters higher than its working range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Important note: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two magnetic products attract each other from a much further distance than a neodymium and metal combination. The setup of magnet-to-magnet generates a stronger field and a wider radius of operation. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the collision energy is huge. The levitation is slightly lower than the attraction, but still significant.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Figures show shear force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronic devices as well as medical implants. These magnets produce a field that destroys function of digital equipment. Notice: the invisible magnetic field passes through tissues and plastic. Exceptional care must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when working with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains merely a fraction of its perpendicular strength.

2. Steel thickness impact

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

3. Temperature resistance

*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) = 0.43

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 a very powerful plate magnet made of NdFeB material, which, with dimensions of 40x40x15 mm and a weight of 180 g, guarantees premium class connection. This rectangular block with a force of 460.51 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.

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. Watch your fingers! Magnets with a force of 46.94 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 40x40x15 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 46.94 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 40x40x15 / 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 40x40x15 / N38 model is magnetized through the thickness (dimension 15 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 (40x40 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.

The presented product is a neodymium magnet with precisely defined parameters: 40 mm (length), 40 mm (width), and 15 mm (thickness). The key parameter here is the holding force amounting to approximately 46.94 kg (force ~460.51 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

Apart from their superior magnetism, neodymium magnets have these key benefits:

They do not lose power, even after approximately 10 years – the drop in power is only ~1% (theoretically),
They retain their magnetic properties even under strong external field,
In other words, due to the shiny layer of silver, the element gains a professional look,
Magnets exhibit excellent magnetic induction on the surface,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Due to the option of free shaping and adaptation to custom projects, neodymium magnets can be created in a variety of geometric configurations, which increases their versatility,
Significant place in modern technologies – they are utilized in mass storage devices, motor assemblies, diagnostic systems, as well as modern systems.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

Problematic aspects of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. 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 those in rubber or plastics, which secure oxidation as well as corrosion.
We recommend a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
With mass production the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum holding power of the magnet – what it depends on?

The specified lifting capacity refers to the limit force, recorded under optimal environment, specifically:

using a base made of high-permeability steel, serving as a magnetic yoke
possessing a thickness of minimum 10 mm to avoid saturation
characterized by even structure
with zero gap (without coatings)
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Key elements affecting lifting force

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

Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

Maximum temperature

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

GPS and phone interference

Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.

Choking Hazard

Only for adults. Small elements can be swallowed, causing serious injuries. Keep away from kids and pets.

Eye protection

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them breaking into shards.

Implant safety

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Fire warning

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

Nickel allergy

Certain individuals experience a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling may cause an allergic reaction. It is best to wear protective gloves.

Crushing risk

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

Electronic devices

Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Safe operation

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