Pulling power weakens significantly with every subsequent millimeter of gap. Note that even the smallest gap (e.g., dirt, varnish, dust) noticeably reduces the pull force. Magnets hold strongest during direct contact; air break nullifies the power. Notice how quickly the pull force drop, when the magnet does not touch tightly to the steel surface. When calculating the arrangement, eliminate redundant distances.

The following data calculates the estimated force necessary to initiate the sliding of the magnet downwards on a upright steel wall (assuming typical friction coefficient). This parameter depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 15x15x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.76 kg / 3.88 pounds 1761.0 g / 17.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.17 kg / 2.59 pounds 1174.0 g / 11.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.59 kg / 1.29 pounds 587.0 g / 5.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.94 kg / 6.47 pounds 2935.0 g / 28.8 N

When mounting a element on a vertical plane (e.g., a car body), it will maintain just approx. 20%-30% of its nominal power. Gravitational force and a low friction coefficient mean that products slip easier than they pull off. Planning a hanger? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the element will give way down under a significantly smaller load. Using a rubber layer can significantly improve the result.

A too thin steel is not enough to absorb the full magnetic flux, which squanders power of the holder. If you install a neodymium to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To squeeze full efficiency of this neodymium's potential, you require a sufficiently solid element of steel. The material oversaturation means that on thin elements (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel dimension according to the table below.

Standard neodymium magnets change their properties power past the thermal threshold. Protect against heat – heat can irreversibly demagnetize this product. With increasing heat, the neodymium's power momentarily lowers. Refrain from using this product near heat sources higher than its operating temperature limit. Too high temperature will result in destruction of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures compared to rod magnets. The danger warning 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 performance. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Remember that when attracting two neodymiums, the collision energy is extreme. The levitation is marginally weaker than the connection force, but still impressive.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Important: Figures show sliding force of two matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to IT equipment as well as medical implants. These NdFeB products produce a flux that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation acts through matter and plastic. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can cause material chips or injury to fingers. Hold the magnet firmly during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when handling with large magnets.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Steel saturation

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

3. Temperature resistance

*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) = 0.40

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.

Model MPL 15x15x5 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. This magnetic block with a force of 57.62 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. Watch your fingers! Magnets with a force of 5.87 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. Thanks to the flat surface and high force (approx. 5.87 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 15x15x5 / N38, we recommend utilizing two-component adhesives (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 clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 15x15x5 / 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.

The presented product is a neodymium magnet with precisely defined parameters: 15 mm (length), 15 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 5.87 kg (force ~57.62 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

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

They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
Neodymium magnets remain highly resistant to loss of magnetic properties caused by external field sources,
A magnet with a smooth nickel surface is more attractive,
Magnetic induction on the working layer of the magnet turns out to be very high,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Thanks to versatility in constructing and the ability to customize to individual projects,
Wide application in future technologies – they are utilized in data components, electromotive mechanisms, precision medical tools, and technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Characteristics of disadvantages of neodymium magnets and proposals for their use:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in realizing nuts and complex shapes in magnets, we propose using cover - magnetic mechanism.
Health risk resulting from small fragments 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 are able to complicate diagnosis medical in case of swallowing.
With large orders the cost of neodymium magnets can be a barrier,

Lifting parameters

Highest magnetic holding force – what affects it?

Magnet power was defined for the most favorable conditions, including:

using a plate made of high-permeability steel, serving as a ideal flux conductor
possessing a massiveness of at least 10 mm to ensure full flux closure
characterized by lack of roughness
with direct contact (no paint)
under axial force vector (90-degree angle)
at temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Real force is affected by specific conditions, mainly (from priority):

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
Surface structure – the more even the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets

Flammability

Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Safe distance

Intense magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Danger to pacemakers

Individuals with a heart stimulator should maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Fragile material

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.

Crushing risk

Big blocks can smash fingers instantly. Do not place your hand betwixt two strong magnets.

Keep away from children

NdFeB magnets are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.

Skin irritation risks

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, cease handling magnets and use protective gear.

Thermal limits

Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.

Caution required

Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and respect their power.

Compass and GPS

Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
