Grip strength decreases drastically with every subsequent millimeter of spacing. Note that even the smallest gap (e.g., contamination, varnish, veneer) noticeably diminishes the holding power. Magnets operate strongest during direct contact; gap weakens the power. Notice how rapidly the load capacity fall, when the magnet does not touch flatly to the steel surface. When designing the mounting, discard unnecessary gaps.

The following data defines the approximate holding capacity necessary to start the slippage of the magnet vertically along a vertical metal surface (considering standard friction). This parameter depends on the gap size between the magnet and the surface.

Raw steel	µ = 0.3 30% Nominalnej Siły	36.00 kg / 79.37 lbs 36003.0 g / 353.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	24.00 kg / 52.92 lbs 24002.0 g / 235.5 N

When placing a holder on a upright plane (e.g., a board), it will maintain barely approx. 20%-30% of nominal attraction strength. Gravity and a weak degree of grip cause that magnets move down faster than they pop off the substrate. Planning a wall mount? Consider that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will give way down under a significantly smaller load. Using a rubber coating can effectively increase the grip.

A thin sheet is not enough to absorb the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a thin surface, the flux will pass right through and the attraction force will be weaker. To squeeze the maximum of this neodymium's power, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the holder works worse. We recommend selecting the steel cross-section according to the table below.

Ordinary NdFeB products irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly damage this magnet. As the temperature rises, the magnet's capacity momentarily drops. Do not use this magnet in hot environments higher than its safe range. Ignoring the limit will lead to destruction of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than long magnets. Red status in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a wider radius of action. Want to build a powerful holder? Apply two magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The repulsion force is marginally weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Estimates demonstrate shear force of two same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a serious hazard to IT equipment as well as medical implants. These NdFeB products generate a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Kinetic force can trigger coating fragments or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when working with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) significantly 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) = 0.38

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 100x40x20 / N38 features a flat shape and professional pulling force, making it an ideal solution for building separators and machines. This magnetic block with a force of 1177.33 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.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 120.01 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 100x40x20 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as fasteners under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 100x40x20 / 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 roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 100x40x20 / N38 model is magnetized axially (dimension 20 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. 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: 100 mm (length), 40 mm (width), and 20 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 120.01 kg (force ~1177.33 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Strengths

Apart from their strong power, neodymium magnets have these key benefits:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnets have extremely high magnetic induction on the surface,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Due to the possibility of flexible forming and customization to unique solutions, NdFeB magnets can be created in a wide range of geometric configurations, which expands the range of possible applications,
Significant place in future technologies – they are commonly used in mass storage devices, drive modules, diagnostic systems, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices

Weaknesses

Problematic aspects of neodymium magnets and proposals for their use:

At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We suggest a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Detachment force of the magnet in optimal conditions – what contributes to it?

The specified lifting capacity refers to the peak performance, obtained under optimal environment, specifically:

with the application of a sheet made of special test steel, ensuring maximum field concentration
whose transverse dimension reaches at least 10 mm
with an ground contact surface
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (in the magnet axis)
in stable room temperature

Magnet lifting force in use – key factors

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

Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.

H&S for magnets

No play value

Strictly keep magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.

Danger to pacemakers

Patients with a pacemaker must keep an safe separation from magnets. The magnetism can stop the operation of the life-saving device.

Impact on smartphones

Be aware: rare earth magnets generate a field that confuses sensitive sensors. Keep a separation from your phone, tablet, and GPS.

Pinching danger

Large magnets can break fingers instantly. Do not place your hand betwixt two strong magnets.

Maximum temperature

Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Electronic hazard

Data protection: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).

Flammability

Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Immense force

Handle with care. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can react.

Fragile material

Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Warning for allergy sufferers

It is widely known that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid direct skin contact or choose encased magnets.
