Grip strength decreases drastically per each millimeter of spacing. Keep in mind that even a very thin break (e.g., contamination, paint, dust) noticeably weakens the grip. Magnetic products work strongest in perfect adhesion; distance nullifies the power. Analyze how rapidly the parameters drop, when the product does not adhere tightly to the steel surface. When planning the arrangement, eliminate additional spacers.

This section presents the theoretical shear load sufficient to cause the downward movement of the magnet downwards on a upright metal surface (considering standard friction). This value depends on the gap size between the magnet and the surface.

When mounting a element on a upright wall (e.g., a car body), it will only hold just about 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that holders move down faster than they detach. Designing a hanger? Consider that the shear force is much weaker than the maximum static pull force. On a smooth steel, the magnet will give way down under a significantly smaller cargo. Application of an anti-slip pad can significantly raise the stability.

A thin sheet is unable to take in the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To squeeze the maximum of this magnet's power, you need a suitably thick backing of metal. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We advise picking the steel dimension from these parameters.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently destroy this product. As the temperature rises, the neodymium's capacity momentarily decreases. Refrain from using this magnet close to heaters exceeding its operating temperature limit. Ignoring the limit will cause destruction of magnetism.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. Such a system of two magnets creates a more powerful interaction and a larger range of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is huge. The levitation is slightly lower than the connection force, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Calculations show shear force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to IT equipment and medical implants. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation penetrates the body and plastic. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or injury to fingers. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when handling with powerful specimens.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Warning: On a vertical surface, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Thermal stability

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.43

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.

Component MPL 40x18x10 SH / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 23.81 kg), this product is available immediately 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. To separate the MPL 40x18x10 SH / 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.

They constitute a key element in the production of generators and material handling systems. 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 40x18x10 SH / 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.

Standardly, the MPL 40x18x10 SH / N38 model is magnetized through the thickness (dimension 10 mm), which means that the N and S poles are located on its largest, flat surfaces. 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 40x18x10 mm, which, at a weight of 54 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 23.81 kg (force ~233.58 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

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

Their strength remains stable, and after around ten years it drops only by ~1% (according to research),
They maintain their magnetic properties even under close interference source,
By using a reflective coating of nickel, the element presents an modern look,
Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to modularity in constructing and the capacity to customize to complex applications,
Huge importance in high-tech industry – they are commonly used in computer drives, electric drive systems, diagnostic systems, also complex engineering applications.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 extremely resistant to heat
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic holder.
Potential hazard resulting from small fragments of magnets can be dangerous, 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 products can complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets can be a barrier,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

The load parameter shown refers to the maximum value, obtained under ideal test conditions, meaning:

on a base made of mild steel, effectively closing the magnetic flux
with a thickness no less than 10 mm
characterized by lack of roughness
under conditions of ideal adhesion (metal-to-metal)
during detachment in a direction perpendicular to the mounting surface
in stable room temperature

Key elements affecting lifting force

In practice, the real power depends on a number of factors, presented from most significant:

Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Plate material – mild steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.

H&S for magnets

Crushing risk

Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!

Heat warning

Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Swallowing risk

Always keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are fatal.

Precision electronics

Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Fragile material

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them cracking into small pieces.

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop working with magnets and use protective gear.

Electronic devices

Very strong magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Do not underestimate power

Be careful. Rare earth magnets attract from a long distance and snap with massive power, often quicker than you can move away.

Life threat

Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Mechanical processing

Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
