Magnetic force decreases drastically with every subsequent millimeter of spacing. Remember that even a very thin break (e.g., contamination, paint, dust) noticeably weakens the grip. Neodymiums work strongest during direct contact; distance kills the force. Notice how rapidly the pull force drop, when the magnet does not adhere directly to the metal substrate. When calculating the mounting, avoid unnecessary gaps.

The table below calculates the approximate holding capacity required to initiate the shifting of the magnet downwards along a vertical steel plate (assuming standard friction coefficient). This value is a function of the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 40x15x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.41 kg / 7.51 pounds 3405.0 g / 33.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.27 kg / 5.00 pounds 2270.0 g / 22.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.14 kg / 2.50 pounds 1135.0 g / 11.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.68 kg / 12.51 pounds 5675.0 g / 55.7 N

When hanging a element on a upright surface (e.g., a car body), it you can count on just about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that magnets slip easier than they detach. Designing a vertical fastening? Note that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will give way down under a much lighter weight. Utilizing a rubberized coating can drastically improve the result.

A thin sheet is incapable of focus the entire magnetic field, which wastes potential of the holder. Should you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To achieve the maximum of this neodymium's potential, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the holder works worse. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets change their properties power past the thermal threshold. Avoid high temperatures – heat can irreversibly destroy this magnet. With increasing heat, the magnet's power momentarily decreases. Avoid using this product close to heaters exceeding its safe range. Too high temperature will lead to irreversible degradation of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnets interact from a wider radius than a neodymium and metal setup. The setup of two magnets produces a massive flux and a further horizon of performance. Planning to create a strong closure? Apply two magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the collision energy is huge. The levitation is slightly lower than the attraction, but still impressive.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Important: Estimates show friction force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Hazards (implants) - precautionary measures

Powerful magnet radiation is a large risk to electronics as well as pacemakers. These neodymiums generate a flux that disrupts operation of digital equipment. Notice: the invisible magnetic field passes through tissues and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are very brittle – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. Use safety goggles when playing with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Thermal stability

*For N38 grade, 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) = 0.26

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 a very powerful plate magnet made of NdFeB material, which, with dimensions of 40x15x5 mm and a weight of 22.5 g, guarantees premium class connection. This magnetic block with a force of 111.37 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 40x15x5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 11.35 kg), they are ideal as hidden locks 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 40x15x5 / N38, we recommend utilizing 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. 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 40x15x5 / N38 model is magnetized axially (dimension 5 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 (40x15 mm), which is ideal for flat mounting. 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: 40 mm (length), 15 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 40x15x5 mm and a self-weight of 22.5 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:

They do not lose strength, even after nearly ten years – the drop in power is only ~1% (theoretically),
Neodymium magnets prove to be remarkably resistant to loss of magnetic properties caused by external interference,
Thanks to the smooth finish, the surface of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
Magnets are characterized by excellent magnetic induction on the working surface,
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...
Thanks to modularity in forming and the capacity to customize to unusual requirements,
Versatile presence in electronics industry – they are utilized in hard drives, electric motors, precision medical tools, as well as industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these products are able to be problematic in diagnostics medical in case of swallowing.
With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum lifting force for a neodymium magnet – what it depends on?

The load parameter shown refers to the limit force, obtained under optimal environment, meaning:

with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
with a cross-section of at least 10 mm
with a surface free of scratches
under conditions of no distance (metal-to-metal)
for force acting at a right angle (pull-off, not shear)
at standard ambient temperature

Lifting capacity in practice – influencing factors

Bear in mind that the application force may be lower depending on the following factors, in order of importance:

Distance (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Plate thickness – too thin plate does not accept the full field, causing part of the power to be wasted into the air.
Steel type – low-carbon steel gives the best results. Alloy steels lower magnetic permeability and lifting capacity.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

GPS Danger

Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Thermal limits

Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and pulling force.

Nickel coating and allergies

Some people experience a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Extended handling might lead to an allergic reaction. It is best to wear protective gloves.

Crushing risk

Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Magnets are brittle

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Keep away from computers

Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).

Keep away from children

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

Combustion hazard

Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Immense force

Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can react.

Pacemakers

For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Caution! Details about risks in the article: Magnet Safety Guide.
