Grip strength decreases sharply with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., dirt, varnish, rust) strongly weakens the grip. Neodymiums work strongest in perfect adhesion; gap kills the power. See how rapidly the parameters plummet, when the product does not touch directly to the steel surface. When calculating the assembly, eliminate additional spacers.

This section shows the approximate holding capacity sufficient to initiate the slippage of the magnet downwards against a upright steel plate (considering typical friction). This parameter is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.14 kg / 15.75 pounds 7143.0 g / 70.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.76 kg / 10.50 pounds 4762.0 g / 46.7 N

When placing a holder on a vertical surface (e.g., a car body), it you can count on barely about 1/5 of nominal attraction strength. Gravity and a weak degree of grip influence the fact that products slide down faster than they pull off. Want to create a vertical fastening? Note that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slip down under a much lighter cargo. Application of an anti-slip layer can significantly raise the stability.

A thin sheet is unable to take in the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's potential, you require a sufficiently solid piece of metal. The saturation effect means that on thin elements (e.g., appliance housings), the holder works worse. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly demagnetize this product. As the temperature rises, the magnet's force briefly decreases. Avoid using this magnet close to ovens exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products interact from a much further distance than a neodymium and metal combination. The setup of magnet-to-magnet generates a stronger field and a further horizon 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 pinch force is huge. The repulsion force is a bit weaker than the attraction, but still significant.
*Flux density between like poles drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Results show friction force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronics and medical implants. These neodymiums generate a flux that destroys function of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Exceptional care 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, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can cause material chips or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when working with powerful specimens.

Environment	Effective steel pull	Effect

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

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

3. Temperature resistance

*For N38 grade, the safety 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.

Component MPL 40x18x10 SH / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 233.58 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 strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x18x10 SH / 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. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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 40x18x10 SH / N38 model is magnetized axially (dimension 10 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 40x18x10 mm, which, at a weight of 54 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 40x18x10 mm and a self-weight of 54 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

Their strength is maintained, and after around 10 years it drops only by ~1% (theoretically),
They have excellent resistance to magnetism drop as a result of opposing magnetic fields,
The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
Magnets have maximum magnetic induction on the surface,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
In view of the ability of flexible shaping and customization to individualized needs, neodymium magnets can be modeled in a wide range of forms and dimensions, which makes them more universal,
Fundamental importance in future technologies – they find application in mass storage devices, electromotive mechanisms, advanced medical instruments, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Cons

Drawbacks and weaknesses of neodymium magnets: application proposals

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power 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 when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing nuts and complicated shapes in magnets, we propose using casing - magnetic holder.
Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical after entering the body.
With large orders the cost of neodymium magnets can be a barrier,

Holding force characteristics

Best holding force of the magnet in ideal parameters – what affects it?

The force parameter is a measurement result conducted under specific, ideal conditions:

with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
with a thickness minimum 10 mm
with an polished contact surface
with zero gap (no coatings)
during pulling in a direction perpendicular to the mounting surface
at ambient temperature room level

Key elements affecting lifting force

Holding efficiency is affected by specific conditions, such as (from most important):

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Element 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 finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Keep away from children

Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.

Dust is flammable

Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Finger safety

Large magnets can break fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.

Shattering risk

NdFeB magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them shattering into small pieces.

Demagnetization risk

Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Implant safety

People with a ICD have to maintain an safe separation from magnets. The magnetic field can stop the functioning of the implant.

Handling rules

Use magnets consciously. Their huge power can surprise even professionals. Plan your moves and respect their power.

Allergic reactions

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness occurs, cease working with magnets and wear gloves.

Precision electronics

GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.

Cards and drives

Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
