Magnetic force weakens drastically per each millimeter of spacing. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) significantly weakens the grip. Neodymiums operate most effectively in perfect adhesion; distance kills the force. Notice how quickly the parameters fall, when the magnet does not adhere directly to the metal substrate. When calculating the assembly, avoid redundant distances.

The table below calculates the theoretical shear load necessary to cause the downward movement of the magnet downwards against a upright steel wall (considering typical friction). The holding force is a function of the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MPL 40x40x15 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	14.08 kg / 31.05 pounds 14082.0 g / 138.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	9.39 kg / 20.70 pounds 9388.0 g / 92.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	4.69 kg / 10.35 pounds 4694.0 g / 46.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	23.47 kg / 51.74 pounds 23470.0 g / 230.2 N

When hanging a holder on a upright surface (e.g., a car body), it will maintain just about 20%-30% of nominal attraction strength. Gravitational force and a weak degree of grip mean that magnets move down faster than they detach. Planning a vertical fastening? Remember that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter load. Using a rubber pad can effectively improve the result.

12 mm	100%	46.94 kg / 103.48 pounds 46940.0 g / 460.5 N

A thin sheet is unable to take in the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this neodymium's potential, you need a suitably thick element of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product holds weaker. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose power above the temperature limit. Watch out for overheating – heat can irreversibly damage this magnet. With increasing heat, the neodymium's capacity temporarily lowers. Avoid using this magnet close to ovens exceeding its safe range. Ignoring the limit will cause destruction of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets creates a more powerful interaction and a larger range of operation. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*Field value between like poles drops to ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Note: Results demonstrate friction force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Hazards (implants) - warnings
MPL 40x40x15 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	20.5 cm
Hearing aid	10 Gs (1.0 mT)	16.0 cm
Timepiece	20 Gs (2.0 mT)	12.5 cm

A strong magnetic field is a large risk to electronic devices as well as pacemakers. These magnets generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and housings. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

50 mm	36.50 km/h (10.14 m/s)	9.25 J
100 mm	51.50 km/h (14.31 m/s)	18.42 J

Magnetic elements are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. 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.

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

1. Shear force

*Caution: On a vertical wall, the magnet retains just approx. 20-30% of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

*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) = 0.43

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.

824.10 ZŁ brutto / pcs

Model MPL 40x40x15 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 46.94 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 46.94 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. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 40x40x15 / N38, it is best to use strong epoxy glues (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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 40x40x15 / N38 model is magnetized axially (dimension 15 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 (40x40 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.

This model is characterized by dimensions 40x40x15 mm, which, at a weight of 180 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 46.94 kg (force ~460.51 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Benefits

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

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
Neodymium magnets are characterized by highly resistant to loss of magnetic properties caused by external magnetic fields,
By covering with a smooth layer of gold, the element gains an elegant look,
Neodymium magnets ensure maximum magnetic induction on a their surface, which increases force concentration,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to flexibility in shaping and the ability to adapt to specific needs,
Huge importance in modern technologies – they are utilized in computer drives, motor assemblies, advanced medical instruments, and multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in realizing nuts and complicated forms in magnets, we propose using a housing - magnetic mechanism.
Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these devices can disrupt the diagnostic process medical after entering the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what it depends on?

Breakaway force is the result of a measurement for the most favorable conditions, taking into account:

with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
possessing a massiveness of minimum 10 mm to avoid saturation
with an polished touching surface
with total lack of distance (no coatings)
for force applied at a right angle (in the magnet axis)
in temp. approx. 20°C

Magnet lifting force in use – key factors

Bear in mind that the application force will differ influenced by elements below, starting with the most relevant:

Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Health Danger

Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Machining danger

Powder created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Crushing risk

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Avoid contact if allergic

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.

Shattering risk

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Do not underestimate power

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

Swallowing risk

Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.

Data carriers

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

Keep away from electronics

A powerful magnetic field disrupts the operation of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.

Thermal limits

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
