Magnetic force drops sharply with every mm of spacing. Keep in mind that even the smallest gap (e.g., dirt, paint, dust) significantly reduces the pull force. Neodymiums hold most effectively in perfect adhesion; distance weakens the force. Observe how quickly the pull force plummet, when the magnet does not adhere directly to the steel surface. When planning the arrangement, discard additional spacers.

The following data shows the estimated shear load sufficient to start the downward movement of the magnet down against a upright steel plate (considering typical friction). This parameter varies with the separation distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MPL 15x2x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.20 kg / 0.45 lbs 204.0 g / 2.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.14 kg / 0.30 lbs 136.0 g / 1.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.15 lbs 68.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.34 kg / 0.75 lbs 340.0 g / 3.3 N

When mounting a magnet on a upright wall (e.g., a fridge), it will maintain only approx. 1/5 of its maximum pull force. Gravity and a low friction coefficient cause that magnets slide down easier than they pull off. Designing a wall mount? Note that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will slide down under a noticeably lighter weight. Utilizing a rubberized layer can effectively improve the result.

12 mm	100%	0.68 kg / 1.50 lbs 680.0 g / 6.7 N

A thin metal plate is not enough to focus the entire magnetic field, which squanders power of the magnet. Should you mount a strong magnet to a weak sheet, the flux will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's potential, you need a suitably thick backing of steel. The saturation effect means that on delicate walls (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products change their properties parameters past the thermal threshold. Avoid high temperatures – high temperature can irreversibly destroy this product. With every degree above norm, the magnet's power momentarily decreases. Do not use this product close to ovens higher than its safe range. Too high temperature will result in irreversible degradation of magnetic properties.

*Important note: Thermal stability is determined by both grade, but also on the magnet's shape. Thin magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and steel setup. Such a system of magnet-to-magnet generates a stronger field and a larger range of operation. Want to build a strong closure? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the impact force is massive. The levitation is a bit weaker than the connection force, but still large.
*Field value between like poles reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Results demonstrate friction force of dual matching magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronic devices as well as pacemakers. These NdFeB products generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or injury to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with large magnets.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Shear force

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Thermal stability

*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) = 1.54

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 15x2x30 mm and a weight of 6.75 g, guarantees the highest quality connection. This magnetic block with a force of 6.68 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.

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

Plate magnets MPL 15x2x30 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 0.68 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 15x2x30 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 15x2x30 / N38 model is magnetized through the thickness (dimension 30 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (15x2 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 15 mm (length), 2 mm (width), and 30 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 0.68 kg (force ~6.68 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

Apart from their superior holding force, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
They feature excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of exact creating and modifying to defined needs,
Universal use in modern technologies – they are commonly used in magnetic memories, electric drive systems, precision medical tools, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in compact constructions

Cons

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in force. 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 rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
Health risk resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these products can complicate diagnosis medical after entering the body.
Due to complex production process, their price exceeds standard values,

Pull force analysis

Maximum lifting force for a neodymium magnet – what contributes to it?

Magnet power was determined for ideal contact conditions, including:

with the use of a yoke made of special test steel, guaranteeing maximum field concentration
whose transverse dimension equals approx. 10 mm
with an polished contact surface
without any air gap between the magnet and steel
for force applied at a right angle (in the magnet axis)
in temp. approx. 20°C

Practical lifting capacity: influencing factors

Please note that the working load will differ influenced by the following factors, starting with the most relevant:

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.

Precautions when working with NdFeB magnets

Demagnetization risk

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

Threat to navigation

Note: rare earth magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, device, and navigation systems.

Fire warning

Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Keep away from computers

Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

Material brittleness

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Pinching danger

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Adults only

Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from children and animals.

Allergy Warning

Some people experience a contact allergy to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause dermatitis. We strongly advise wear protective gloves.

Implant safety

For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Caution required

Be careful. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.
