Pulling power drops drastically per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) strongly diminishes the holding power. Magnets hold most effectively during direct contact; distance weakens the power. Observe how flashily the load capacity fall, when the product does not adhere flatly to the metal substrate. When designing the assembly, eliminate unnecessary gaps.

The following data indicates the approximate force necessary to start the shifting of the magnet down on a vertical metal surface (assuming typical friction). This value is relative to the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.81 kg / 8.39 pounds 3807.0 g / 37.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.54 kg / 5.60 pounds 2538.0 g / 24.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.27 kg / 2.80 pounds 1269.0 g / 12.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	6.35 kg / 13.99 pounds 6345.0 g / 62.2 N

When placing a holder on a upright plane (e.g., a board), it will only hold only approx. 20%-30% of nominal attraction strength. Gravity and a low friction coefficient cause that holders slip faster than they detach. Designing a wall mount? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the element will slide down under a noticeably lighter load. Application of an anti-slip layer can drastically raise the stability.

A thin sheet is not enough to focus the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To utilize the maximum of this magnet's potential, you require a sufficiently solid piece of steel. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the magnet works worse. We recommend selecting the steel cross-section according to the table below.

Classic neodymiums lose strength after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly damage this product. As the temperature rises, the neodymium's power temporarily drops. Avoid using this product near heat sources higher than its operating temperature limit. Exceeding the critical threshold will cause destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) are more susceptible to demagnetization 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 strong neodymiums attract each other from a much further distance than a neodymium and metal setup. Such a system of two magnets produces a massive flux and a larger range of operation. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still impressive.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Figures refer to friction force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to electronics as well as medical implants. These NdFeB products generate a field that destroys function of digital equipment. Be aware: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can cause material chips or injury to skin. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses 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!

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

1. Sliding resistance

*Caution: On a vertical wall, the magnet retains just ~20% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces 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) = 0.21

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.

Component MPL 50x20x5 / N38 features a low profile and professional pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 124.48 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.

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 50x20x5 / 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.

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.

Standardly, the MPL 50x20x5 / N38 model is magnetized axially (dimension 5 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 50x20x5 mm, which, at a weight of 37.5 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 12.69 kg (force ~124.48 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Advantages

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

They retain magnetic properties for nearly 10 years – the drop is just ~1% (in theory),
They have excellent resistance to magnetic field loss when exposed to external fields,
Thanks to the shiny finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom forming and optimizing to concrete requirements,
Key role in advanced technology sectors – they find application in data components, electromotive mechanisms, medical equipment, as well as multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in producing threads and complex forms in magnets, we propose using casing - magnetic mount.
Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

Magnet power was determined for the most favorable conditions, assuming:

with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
possessing a massiveness of min. 10 mm to ensure full flux closure
characterized by lack of roughness
without the slightest air gap between the magnet and steel
under vertical application of breakaway force (90-degree angle)
in temp. approx. 20°C

Determinants of lifting force in real conditions

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

Distance (betwixt the magnet and the plate), since even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust or debris).
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost to the other side.
Chemical composition of the base – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.

Warnings

Bone fractures

Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.

Machining danger

Dust produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Phone sensors

GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Health Danger

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Sensitization to coating

A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching may cause skin redness. We recommend wear safety gloves.

Adults only

Neodymium magnets are not toys. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which poses a critical condition and requires immediate surgery.

Maximum temperature

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

Risk of cracking

NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them breaking into shards.

Threat to electronics

Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Conscious usage

Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
