Grip strength decreases sharply per each millimeter of distance. Note that even a microscopic distance (e.g., contamination, paint, veneer) strongly weakens the grip. Magnets hold optimally in perfect adhesion; gap drastically cuts the force. Observe how flashily the load capacity fall, when the product does not touch directly to the steel surface. When calculating the mounting, eliminate redundant distances.

The table below calculates the estimated weight limit necessary to initiate the shifting of the magnet downwards on a upright steel wall (considering typical friction coefficient). This value is a function of the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 30x20x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.28 kg / 16.05 lbs 7281.0 g / 71.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.85 kg / 10.70 lbs 4854.0 g / 47.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.43 kg / 5.35 lbs 2427.0 g / 23.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	12.14 kg / 26.75 lbs 12135.0 g / 119.0 N

When placing a element on a vertical surface (e.g., a car body), it will only hold just approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient cause that holders slide down faster than they detach. Planning a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will slide down under a significantly smaller load. Application of an anti-slip coating can significantly raise the stability.

12 mm	100%	24.27 kg / 53.51 lbs 24270.0 g / 238.1 N

A too thin steel is unable to conduct the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To squeeze the maximum of this magnet's potential, you require a sufficiently solid element of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the magnet holds weaker. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Protect against heat – heat can irreversibly damage this product. As the temperature rises, the magnet's force momentarily decreases. Refrain from using this product close to heaters higher than its working range. Too high temperature will cause permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel combination. Such a system of two magnets produces a massive flux and a further horizon of action. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the impact force is massive. The levitation is marginally weaker than the attraction, but still large.
*Field value between like poles drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Important: Estimates apply to shear force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a large risk to electronics and medical implants. These NdFeB products generate a field that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation penetrates the body and plastic. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - warning
MPL 30x20x20 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	17.96 km/h (4.99 m/s)	1.12 J
30 mm	28.76 km/h (7.99 m/s)	2.87 J
50 mm	37.04 km/h (10.29 m/s)	4.76 J
100 mm	52.37 km/h (14.55 m/s)	9.52 J

NdFeB products are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can cause material chips or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering 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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Warning: On a vertical wall, the magnet holds just ~20% of its perpendicular strength.

2. Steel thickness impact

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

3. Thermal stability

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.74

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.

SM 32x450 [2xM8] / N42 - magnetic separator

1340.70 ZŁ brutto / pcs

Model MPL 30x20x20 / N38 features a low profile and professional pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 24.27 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.

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 24.27 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 30x20x20 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. 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. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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 30x20x20 / N38 model is magnetized through the thickness (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. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 30x20x20 mm, which, at a weight of 90 g, makes it an element with high energy density. It is a magnetic block with dimensions 30x20x20 mm and a self-weight of 90 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros and cons of neodymium magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain full power for nearly ten years – the drop is just ~1% (based on simulations),
Magnets effectively protect themselves against demagnetization caused by foreign field sources,
The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to present itself better,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Possibility of individual modeling and adjusting to defined needs,
Versatile presence in modern industrial fields – they find application in HDD drives, drive modules, diagnostic systems, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions

Limitations

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating threads and complicated forms in magnets, we recommend using cover - magnetic holder.
Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum holding power of the magnet – what it depends on?

Breakaway force was defined for the most favorable conditions, taking into account:

on a block made of structural steel, optimally conducting the magnetic field
with a thickness of at least 10 mm
with an ideally smooth contact surface
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction perpendicular to the plane
at ambient temperature room level

Lifting capacity in practice – influencing factors

In real-world applications, the actual lifting capacity results from several key aspects, ranked from crucial:

Clearance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Load vector – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped to the other side.
Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.

H&S for magnets

Metal Allergy

It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose encased magnets.

Flammability

Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Safe operation

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Danger to the youngest

NdFeB magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which poses a critical condition and necessitates immediate surgery.

Material brittleness

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Demagnetization risk

Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

Compass and GPS

Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Hand protection

Large magnets can crush fingers instantly. Do not put your hand betwixt two attracting surfaces.

Threat to electronics

Equipment safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Implant safety

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
