Grip strength decreases significantly with every mm of gap. Note that even the smallest gap (e.g., dirt, paint, dust) strongly weakens the grip. Magnets operate strongest in perfect adhesion; gap kills the force. See how rapidly the load capacity fall, when the product does not adhere flatly to the metal substrate. When planning the mounting, eliminate unnecessary gaps.

This section defines the approximate weight limit necessary to start the sliding of the magnet downwards along a upright metal surface (considering typical friction coefficient). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MPL 40x10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.79 kg / 6.16 LBS 2793.0 g / 27.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.86 kg / 4.11 LBS 1862.0 g / 18.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.93 kg / 2.05 LBS 931.0 g / 9.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.66 kg / 10.26 LBS 4655.0 g / 45.7 N

When mounting a holder on a vertical surface (e.g., a car body), it will maintain just approx. 1/5 of nominal attraction strength. Gravity and a weak degree of grip cause that products slip faster than they detach. Want to create a wall mount? Remember that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller weight. Using a rubber layer can effectively improve the result.

A too thin steel is incapable of absorb the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a weak sheet, the field will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's potential, you require a sufficiently solid element of metal. The material oversaturation means that on sheet metal structures (e.g., car bodies), the product holds weaker. We advise picking the steel cross-section based on the following data.

Ordinary NdFeB products change their properties parameters above the temperature limit. Watch out for overheating – high temperature can permanently damage this product. With increasing heat, the magnet's force temporarily decreases. Refrain from using this product near heat sources exceeding its working range. Too high temperature will lead to destruction of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and steel setup. The connection of two magnets generates a stronger field and a further horizon of operation. Want to build a powerful holder? Apply two magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Calculations apply to sliding force of two identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to IT equipment and medical implants. These neodymiums generate a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a collision with steel causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can cause material chips or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Wear eye protection when handling with large magnets.

Warning: 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

*Note: On a vertical wall, the magnet retains merely a fraction of its nominal pull.

2. Steel saturation

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

3. Temperature resistance

*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 an extremely strong plate magnet made of NdFeB material, which, with dimensions of 40x10x4 mm and a weight of 12 g, guarantees premium class connection. As a block magnet with high power (approx. 9.31 kg), this product is available immediately from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures 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 9.31 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.

Plate magnets MPL 40x10x4 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. 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 40x10x4 / N38, we recommend utilizing 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 40x10x4 / N38 model is magnetized axially (dimension 4 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 (40x10 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 40x10x4 mm, which, at a weight of 12 g, makes it an element with high energy density. It is a magnetic block with dimensions 40x10x4 mm and a self-weight of 12 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They do not lose power, even during nearly ten years – the drop in power is only ~1% (theoretically),
They are extremely resistant to demagnetization induced by external magnetic fields,
In other words, due to the smooth surface of nickel, the element gains a professional look,
Magnets are characterized by huge magnetic induction on the surface,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom creating as well as modifying to defined requirements,
Wide application in innovative solutions – they find application in mass storage devices, electric drive systems, precision medical tools, and multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of NdFeB magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited ability of producing threads in the magnet and complex forms - preferred is a housing - magnet mounting.
Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

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

Holding force of 9.31 kg is a measurement result conducted under standard conditions:

on a block made of mild steel, optimally conducting the magnetic flux
whose transverse dimension is min. 10 mm
with a plane perfectly flat
without any insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
at standard ambient temperature

Magnet lifting force in use – key factors

Effective lifting capacity impacted by specific conditions, including (from priority):

Clearance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets

Heat warning

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Handling rules

Use magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their power.

Protective goggles

Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Fire warning

Powder produced during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Do not give to children

Absolutely keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are very dangerous.

Pinching danger

Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.

GPS and phone interference

Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Protect data

Avoid bringing magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Nickel allergy

Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and choose versions in plastic housing.

Pacemakers

Warning for patients: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Warning! More info about hazards in the article: Magnet Safety Guide.
