Grip strength weakens sharply with every mm of gap. Keep in mind that every additional insulation layer (e.g., dirt, paint, dust) strongly diminishes the holding power. Neodymiums hold strongest in perfect adhesion; distance nullifies the force. Analyze how rapidly the load capacity fall, when the magnet does not touch tightly to the steel surface. When designing the arrangement, eliminate unnecessary gaps.

The table below calculates the estimated weight limit sufficient to cause the slippage of the magnet downwards against a vertical steel wall (assuming standard friction). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 12x10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.04 kg / 2.28 lbs 1035.0 g / 10.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.69 kg / 1.52 lbs 690.0 g / 6.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.35 kg / 0.76 lbs 345.0 g / 3.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.73 kg / 3.80 lbs 1725.0 g / 16.9 N

When hanging a magnet on a vertical wall (e.g., a fridge), it you can count on barely approx. 1/5 of its nominal power. Gravitational force as well as a weak degree of grip mean that magnets slip easier than they pull off. Designing a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the element will give way down under a much lighter weight. Utilizing a rubberized pad can drastically increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection

2 mm	50%	1.73 kg / 3.80 lbs 1725.0 g / 16.9 N
3 mm	75%	2.59 kg / 5.70 lbs 2587.5 g / 25.4 N
5 mm	100%	3.45 kg / 7.61 lbs 3450.0 g / 33.8 N
10 mm	100%	3.45 kg / 7.61 lbs 3450.0 g / 33.8 N
11 mm	100%	3.45 kg / 7.61 lbs 3450.0 g / 33.8 N
12 mm	100%	3.45 kg / 7.61 lbs 3450.0 g / 33.8 N

A too thin steel is unable to focus the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you need a suitably thick element of steel. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the product works worse. We recommend selecting the steel cross-section from these parameters.

Ordinary NdFeB products change their properties parameters past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly destroy this product. As the temperature rises, the magnet's power briefly lowers. Refrain from using this product in hot environments higher than its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) may lose charge permanently under lower heat stress than long magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a larger range of operation. Designing a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Remember that when bringing together two magnets, the impact force is massive. The levitation is slightly lower than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Note: Figures show friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a real danger to IT equipment and medical implants. These magnets generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment 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 becomes dangerous. Kinetic force can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Wear eye protection when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Sliding resistance

*Caution: On a vertical surface, the magnet retains only a fraction of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

*For N38 material, the max working temp 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 12x10x4 mm and a weight of 3.6 g, guarantees the highest quality connection. As a block magnet with high power (approx. 3.45 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 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 12x10x4 / 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. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 12x10x4 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 12x10x4 / 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 roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 12x10x4 / N38 model is magnetized through the thickness (dimension 4 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 (12x10 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 12x10x4 mm, which, at a weight of 3.6 g, makes it an element with high energy density. It is a magnetic block with dimensions 12x10x4 mm and a self-weight of 3.6 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of neodymium magnets.

Advantages

Besides their exceptional field intensity, neodymium magnets offer the following advantages:

They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
They possess excellent resistance to magnetism drop due to external magnetic sources,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the surface of the magnet turns out to be very high,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
In view of the ability of free molding and customization to specialized needs, magnetic components can be modeled in a wide range of shapes and sizes, which expands the range of possible applications,
Key role in electronics industry – they are commonly used in computer drives, electric motors, medical equipment, also technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets and proposals for their use:

At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited possibility of making nuts in the magnet and complicated forms - preferred is cover - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these devices can be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

The force parameter is a result of laboratory testing conducted under specific, ideal conditions:

with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
whose transverse dimension is min. 10 mm
with an ideally smooth contact surface
without any insulating layer between the magnet and steel
under vertical force vector (90-degree angle)
at conditions approx. 20°C

Determinants of lifting force in real conditions

In practice, the actual holding force results from a number of factors, presented from the most important:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Warnings

Safe operation

Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them shattering into small pieces.

Finger safety

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Permanent damage

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

Dust explosion hazard

Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.

Swallowing risk

Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.

Keep away from electronics

Be aware: neodymium magnets generate a field that confuses sensitive sensors. Keep a safe distance from your phone, tablet, and GPS.

Cards and drives

Avoid bringing magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.

Pacemakers

Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
