Magnetic force drops significantly with every subsequent millimeter of distance. Keep in mind that every additional insulation layer (e.g., dirt, varnish, veneer) significantly weakens the grip. Neodymiums operate most effectively in perfect adhesion; gap nullifies the force. See how rapidly the load capacity fall, when the product does not adhere tightly to the metal substrate. When designing the assembly, discard unnecessary gaps.

The table below indicates the theoretical holding capacity needed to start the shifting of the magnet down along a upright steel wall (assuming standard friction). The holding force is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 5x5x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.17 kg / 0.38 LBS 174.0 g / 1.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.12 kg / 0.26 LBS 116.0 g / 1.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.06 kg / 0.13 LBS 58.0 g / 0.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.29 kg / 0.64 LBS 290.0 g / 2.8 N

When mounting a holder on a upright surface (e.g., a board), it will only hold only about 1/5 of its nominal power. Gravitational force as well as a weak degree of grip mean that products slip easier than they detach. Planning a wall mount? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slide down under a significantly smaller load. Application of an anti-slip pad can significantly increase the grip.

12 mm	100%	0.58 kg / 1.28 LBS 580.0 g / 5.7 N

A thin sheet cannot conduct the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the field will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's potential, you need a suitably thick piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the holder works worse. We advise picking the steel dimension from these parameters.

Standard neodymium magnets change their properties strength above the temperature limit. Watch out for overheating – heat can irreversibly damage this magnet. As the temperature rises, the neodymium's capacity temporarily decreases. Do not use this magnet close to heaters exceeding its safe range. Ignoring the limit will lead to permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet combination. Such a system of two magnets produces a massive flux and a further horizon of operation. Want to build a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still large.
*Flux density between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Estimates refer to sliding force of dual same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (electronics) - warnings
MPL 5x5x1.5 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	2.5 cm
Hearing aid	10 Gs (1.0 mT)	2.0 cm
Timepiece	20 Gs (2.0 mT)	1.5 cm

Payment card	400 Gs (40.0 mT)	0.5 cm
HDD hard drive	600 Gs (60.0 mT)	0.5 cm

A strong magnetic field is a serious hazard to IT equipment as well as pacemakers. These neodymiums produce a flux that destroys function of sensitive medical devices. Be aware: the unseen radiation penetrates the body and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
MPL 5x5x1.5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	45.91 km/h (12.75 m/s)	0.02 J
30 mm	79.50 km/h (22.08 m/s)	0.07 J
50 mm	102.64 km/h (28.51 m/s)	0.11 J
100 mm	145.15 km/h (40.32 m/s)	0.23 J

Neodymium magnets are very brittle – a strong collision with metal causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can cause material chips or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses 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.

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains only approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) drastically reduces the holding force.

3. Power loss vs temp

*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) = 0.36

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.

Model MPL 5x5x1.5 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 0.58 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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. Watch your fingers! Magnets with a force of 0.58 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 5x5x1.5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 5x5x1.5 / 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. 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 5x5x1.5 / N38 model is magnetized axially (dimension 1.5 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 (5x5 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 5x5x1.5 mm, which, at a weight of 0.28 g, makes it an element with high energy density. It is a magnetic block with dimensions 5x5x1.5 mm and a self-weight of 0.28 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They retain magnetic properties for around ten years – the loss is just ~1% (based on simulations),
Magnets perfectly protect themselves against loss of magnetization caused by foreign field sources,
A magnet with a shiny nickel surface looks better,
Magnets are distinguished by impressive magnetic induction on the outer side,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Possibility of accurate modeling as well as adjusting to individual needs,
Huge importance in advanced technology sectors – they are commonly used in HDD drives, drive modules, precision medical tools, as well as industrial machines.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Weaknesses

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in producing nuts and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum holding power of the magnet – what affects it?

Holding force of 0.58 kg is a result of laboratory testing conducted under the following configuration:

on a base made of mild steel, optimally conducting the magnetic field
possessing a thickness of min. 10 mm to avoid saturation
with an ground contact surface
with total lack of distance (without impurities)
under perpendicular force vector (90-degree angle)
in neutral thermal conditions

What influences lifting capacity in practice

Real force is influenced by specific conditions, such as (from most important):

Distance – existence of foreign body (paint, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Steel grade – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.

H&S for magnets

Phone sensors

Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.

Demagnetization risk

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.

Threat to electronics

Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Combustion hazard

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Safe operation

Use magnets consciously. Their immense force can shock even professionals. Be vigilant and do not underestimate their power.

Medical implants

Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Beware of splinters

Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.

Danger to the youngest

These products are not toys. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.

Finger safety

Protect your hands. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!

Metal Allergy

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.

Attention! Details about hazards in the article: Magnet Safety Guide.
