Grip strength decreases sharply with every mm of spacing. Remember that every additional insulation layer (e.g., contamination, paint, veneer) significantly reduces the pull force. Magnetic products operate most effectively at the point of direct contact; distance nullifies the force. Analyze how rapidly the parameters drop, when the magnet does not adhere directly to the metal substrate. When designing the assembly, eliminate redundant distances.

The table below presents the theoretical shear load necessary to cause the slippage of the magnet down along a vertical steel plate (assuming standard friction). The holding force varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 40x40x15 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	14.08 kg / 31.05 LBS 14082.0 g / 138.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	9.39 kg / 20.70 LBS 9388.0 g / 92.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	4.69 kg / 10.35 LBS 4694.0 g / 46.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	23.47 kg / 51.74 LBS 23470.0 g / 230.2 N

When placing a magnet on a vertical plane (e.g., a car body), it will maintain barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that products slide down faster than they pull off. Planning a wall mount? Remember that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will slide down under a significantly smaller load. Using a rubber coating can drastically improve the result.

A thin sheet is not enough to conduct the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's power, you require a sufficiently solid element of steel. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the product works worse. We advise picking the steel dimension based on the following data.

Classic neodymiums irreversibly lose strength past the thermal threshold. Protect against heat – high temperature can permanently destroy this magnet. With every degree above norm, the magnet's force temporarily decreases. Do not use this product in hot environments exceeding its safe range. Exceeding the critical threshold will result in destruction of magnetism.

*Important note: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a magnet and steel combination. Such a system of magnet-to-magnet generates a stronger field and a larger range of operation. Planning to create a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is massive. The levitation is marginally weaker than the attraction, but still significant.
*The magnetic induction between like poles reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Results refer to shear force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a large risk to electronics as well as pacemakers. These neodymiums generate a flux that destroys function of digital equipment. Be aware: the unseen radiation passes through tissues and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, 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. Impact energy can cause material chips or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when playing with large magnets.

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

1. Vertical hold

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

2. Plate thickness effect

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

3. Temperature resistance

*For N38 grade, 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 an extremely strong plate magnet made of NdFeB material, which, with dimensions of 40x40x15 mm and a weight of 180 g, guarantees premium class connection. As a magnetic bar with high power (approx. 46.94 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 46.94 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 40x40x15 / 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. 46.94 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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. 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 40x40x15 mm, which, at a weight of 180 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 46.94 kg (force ~460.51 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of rare earth magnets.

Pros

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They do not lose strength, even after around ten years – the decrease in strength is only ~1% (according to tests),
Neodymium magnets remain extremely resistant to demagnetization caused by external interference,
A magnet with a smooth silver surface has better aesthetics,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Possibility of accurate shaping as well as modifying to atypical needs,
Key role in future technologies – they are used in computer drives, electric motors, precision medical tools, and modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

What to avoid - cons of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
We suggest casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
Health risk resulting from small fragments 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 tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what it depends on?

Magnet power was determined for the most favorable conditions, taking into account:

with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
with a thickness minimum 10 mm
with an polished touching surface
without the slightest air gap between the magnet and steel
for force acting at a right angle (in the magnet axis)
at ambient temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

Effective lifting capacity is affected by specific conditions, such as (from priority):

Clearance – existence of foreign body (paint, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
Direction of force – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost into the air.
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was measured 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. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Warnings

Respect the power

Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can react.

Fire warning

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

This is not a toy

Neodymium magnets are not toys. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.

Medical implants

For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.

Permanent damage

Avoid heat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Magnet fragility

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Phone sensors

A strong magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.

Warning for allergy sufferers

Some people experience a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching may cause skin redness. We recommend wear protective gloves.

Finger safety

Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.

Keep away from computers

Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
