Pulling power decreases drastically per each millimeter of gap. Remember that even a very thin break (e.g., contamination, varnish, rust) strongly reduces the pull force. Neodymiums hold optimally at the point of direct contact; gap drastically cuts the power. Analyze how rapidly the parameters plummet, when the magnet does not touch tightly to the metal substrate. When planning the assembly, eliminate redundant distances.

The following data calculates the theoretical weight limit necessary to initiate the shifting of the magnet vertically against a vertical steel wall (considering standard friction coefficient). This value varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.78 kg / 3.92 pounds 1778.0 g / 17.4 N

When mounting a element on a upright surface (e.g., a fridge), it will maintain only approx. 20%-30% of nominal attraction strength. Gravity and a low friction coefficient influence the fact that holders move down easier than they detach. Designing a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the element will give way down under a significantly smaller cargo. Utilizing a rubberized layer can significantly improve the result.

A thin metal plate is incapable of take in the entire magnetic field, which weakens actual performance of the holder. Should you install a neodymium to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To achieve 100% of this neodymium's potential, you require a sufficiently solid piece of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the product holds weaker. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets lose strength above the temperature limit. Watch out for overheating – high temperature can irreversibly destroy this product. With every degree above norm, the magnet's power momentarily lowers. Do not use this magnet close to ovens higher than its working range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products interact from a much further distance than a magnet and sheet combination. Such a system of two magnets generates a stronger field and a larger range of performance. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the collision energy is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Figures apply to sliding force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to electronic devices as well as medical implants. These magnets generate a field that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and glass. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when working with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Caution: On a vertical surface, the magnet retains merely approx. 20-30% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.35

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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.

1193.10 ZŁ brutto / pcs

Model MPL 30x10x5 / N38 features a flat shape and professional pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 8.89 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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. Watch your fingers! Magnets with a force of 8.89 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.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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.

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: 30 mm (length), 10 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 8.89 kg (force ~87.23 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of neodymium magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:

Their power is durable, and after approximately ten years it drops only by ~1% (according to research),
They do not lose their magnetic properties even under strong external field,
By covering with a lustrous coating of nickel, the element acquires an elegant look,
Neodymium magnets ensure maximum magnetic induction on a small area, which ensures high operational effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
Possibility of custom creating as well as adapting to complex requirements,
Huge importance in advanced technology sectors – they are utilized in data components, brushless drives, diagnostic systems, as well as modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

Information about lifting capacity was defined for the most favorable conditions, including:

using a plate made of low-carbon steel, functioning as a magnetic yoke
with a cross-section minimum 10 mm
with a surface free of scratches
with zero gap (without paint)
during pulling in a direction perpendicular to the mounting surface
at temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

During everyday use, the actual lifting capacity depends on a number of factors, listed from crucial:

Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes 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.
Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be wasted into the air.
Chemical composition of the base – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Allergic reactions

Some people experience a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact may cause a rash. It is best to use safety gloves.

GPS and phone interference

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Medical implants

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Fire warning

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Permanent damage

Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).

Handling guide

Handle with care. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can react.

Physical harm

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

Electronic devices

Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Eye protection

Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Danger to the youngest

These products are not intended for children. Eating several magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
