Grip strength weakens sharply with every subsequent millimeter of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, veneer) strongly reduces the pull force. Magnetic products hold strongest in perfect adhesion; gap kills the force. See how rapidly the load capacity fall, when the product does not touch flatly to the steel surface. When calculating the assembly, eliminate unnecessary gaps.

This section indicates the theoretical shear load needed to initiate the sliding of the magnet vertically against a vertical metal surface (assuming typical friction). This parameter depends on the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 40x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.55 kg / 7.84 lbs 3555.0 g / 34.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.37 kg / 5.22 lbs 2370.0 g / 23.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.19 kg / 2.61 lbs 1185.0 g / 11.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.93 kg / 13.06 lbs 5925.0 g / 58.1 N

When mounting a magnet on a vertical wall (e.g., a car body), it you can count on barely approx. 1/5 of its maximum pull force. Gravity as well as a weak degree of grip cause that products slip easier than they pull off. Want to create a vertical fastening? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter load. Application of an anti-slip coating can significantly raise the stability.

A too thin steel is incapable of absorb the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you need a suitably thick element of steel. The saturation effect means that on thin elements (e.g., appliance housings), the holder works worse. We suggest choosing the steel thickness according to the table below.

Standard neodymium magnets irreversibly lose parameters above the temperature limit. Protect against heat – high temperature can permanently damage this magnet. As the temperature rises, the magnet's capacity briefly lowers. Avoid using this magnet near heat sources higher than its safe range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Important note: 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. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a neodymium and metal combination. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Designing 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 significant.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Figures refer to friction force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a serious hazard to IT equipment as well as medical implants. These neodymiums produce a flux that destroys function of sensitive medical devices. 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, HDD media, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning
MPL 40x10x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.99 km/h (8.05 m/s)	0.49 J
30 mm	49.12 km/h (13.64 m/s)	1.40 J
50 mm	63.39 km/h (17.61 m/s)	2.33 J
100 mm	89.64 km/h (24.90 m/s)	4.65 J

Magnetic elements are very brittle – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet 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. Use safety goggles when handling with large magnets.

Rust risk: 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. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains merely ~20% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.31

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.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 40x10x5 mm and a weight of 15 g, guarantees the highest quality connection. This magnetic block with a force of 116.27 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 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 11.85 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as fasteners 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

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.

This model is characterized by dimensions 40x10x5 mm, which, at a weight of 15 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 40x10x5 mm and a self-weight of 15 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Pros

Besides their tremendous pulling force, neodymium magnets offer the following advantages:

They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
They feature excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
In other words, due to the glossy finish of silver, the element becomes visually attractive,
They are known for high magnetic induction at the operating surface, making them more effective,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Thanks to freedom in forming and the capacity to modify to specific needs,
Versatile presence in advanced technology sectors – they are commonly used in computer drives, drive modules, medical equipment, and multitasking production systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we advise 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 power. 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
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing nuts and complex forms in magnets, we propose using cover - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
Due to neodymium price, their price is relatively high,

Holding force characteristics

Highest magnetic holding force – what contributes to it?

Breakaway force was determined for optimal configuration, assuming:

on a plate made of structural steel, optimally conducting the magnetic field
possessing a thickness of at least 10 mm to ensure full flux closure
with a plane free of scratches
under conditions of ideal adhesion (metal-to-metal)
during pulling in a direction perpendicular to the mounting surface
at temperature room level

Practical lifting capacity: influencing factors

Real force is influenced by working environment parameters, mainly (from most important):

Air gap (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Chemical composition of the base – low-carbon steel gives the best results. Alloy steels lower magnetic permeability and lifting capacity.
Plate texture – ground elements ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Safe handling of neodymium magnets

Machining danger

Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Keep away from children

Neodymium magnets are not toys. Eating a few magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.

Cards and drives

Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).

Magnet fragility

Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Handling rules

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Pinching danger

Large magnets can crush fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Warning for allergy sufferers

Certain individuals have a sensitization to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in a rash. We recommend use protective gloves.

Permanent damage

Keep cool. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Impact on smartphones

Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Danger to pacemakers

People with a ICD have to maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
