Grip strength decreases sharply per each millimeter of distance. Note that even a microscopic distance (e.g., dirt, varnish, dust) strongly reduces the pull force. Magnets work strongest in perfect adhesion; air break kills the force. Observe how rapidly the pull force fall, when the product does not touch tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

The table below indicates the estimated force needed to start the downward movement of the magnet downwards against a vertical steel plate (considering standard friction coefficient). This value is a function of the gap size between the magnet and the metal.

When hanging a holder on a vertical wall (e.g., a car body), it will maintain barely approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that products move down faster than they pull off. Designing a vertical fastening? Remember that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter cargo. Utilizing a rubberized coating can drastically improve the result.

A thin sheet is incapable of focus the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a too thin substrate, 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 effect means that on delicate walls (e.g., appliance housings), the magnet works worse. We recommend selecting the steel cross-section according to the table below.

Classic neodymiums change their properties power past the thermal threshold. Protect against heat – excessive heat can permanently demagnetize this product. With increasing heat, the magnet's capacity briefly lowers. Avoid using this product close to ovens exceeding its working range. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet produces a massive flux and a wider radius of performance. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is a bit weaker than the attraction, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Calculations apply to shear force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field is a large risk to electronic devices as well as medical implants. These neodymiums produce a field that destroys function of digital equipment. Remember: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or injury to skin. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when handling with powerful specimens.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Shear force

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

2. Steel saturation

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

3. Temperature resistance

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.84

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 20x20x20 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 15.40 kg), this product is available immediately from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 20x20x20 / 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 wind generators and material handling systems. Thanks to the flat surface and high force (approx. 15.40 kg), they are ideal as closers in furniture making and mounting elements in automation. 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 20x20x20 / N38, it is best to use strong epoxy glues (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.

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.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 20 mm (width), and 20 mm (thickness). The key parameter here is the holding force amounting to approximately 15.40 kg (force ~151.12 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Benefits

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

Their strength is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
Thanks to the shiny finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an elegant appearance,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of detailed machining as well as adjusting to individual conditions,
Universal use in electronics industry – they find application in mass storage devices, electric motors, medical devices, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices

Disadvantages

Disadvantages of NdFeB magnets:

At strong impacts they can crack, 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 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in creating nuts and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical after entering the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity represents the peak performance, recorded under ideal test conditions, meaning:

using a plate made of high-permeability steel, functioning as a magnetic yoke
whose transverse dimension reaches at least 10 mm
with an ground contact surface
without any clearance between the magnet and steel
under vertical force vector (90-degree angle)
at room temperature

Magnet lifting force in use – key factors

Please note that the magnet holding will differ depending on the following factors, in order of importance:

Distance – the presence of foreign body (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Heat – neodymium magnets 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 carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safe handling of neodymium magnets

Magnets are brittle

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Heat warning

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Data carriers

Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Finger safety

Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Pacemakers

Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

Warning for allergy sufferers

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

Conscious usage

Use magnets with awareness. Their powerful strength can surprise even professionals. Stay alert and do not underestimate their power.

Phone sensors

Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.

Danger to the youngest

NdFeB magnets are not toys. Swallowing multiple magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.

Dust explosion hazard

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Warning! Details about risks in the article: Safety of working with magnets.
