Grip strength decreases drastically per each millimeter of gap. Keep in mind that even a microscopic distance (e.g., contamination, paint, veneer) significantly weakens the grip. Magnets work optimally during direct contact; gap drastically cuts the force. Notice how quickly the pull force fall, when the product does not touch tightly to the steel surface. When calculating the arrangement, discard unnecessary gaps.

The table below presents the theoretical weight limit needed to initiate the shifting of the magnet down on a upright steel wall (considering typical friction coefficient). This parameter depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (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 LBS 3405.0 g / 33.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.27 kg / 5.00 LBS 2270.0 g / 22.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.14 kg / 2.50 LBS 1135.0 g / 11.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.68 kg / 12.51 LBS 5675.0 g / 55.7 N

When hanging a element on a upright plane (e.g., a board), it will maintain only approx. 1/5 of its nominal power. Gravitational force as well as a low friction coefficient mean that magnets slide down faster than they pop off the substrate. Designing a vertical fastening? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a noticeably lighter load. Utilizing a rubberized pad can significantly increase the grip.

A thin sheet cannot take in the full magnetic flux, which weakens actual performance of the holder. If you install a neodymium to a weak sheet, the flux will penetrate right through and the pull force will drop sharply. To squeeze 100% of this magnet's power, you require a sufficiently solid backing of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the holder works worse. We advise picking the steel thickness from these parameters.

Ordinary NdFeB products lose power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly damage this magnet. With increasing heat, the neodymium's capacity momentarily decreases. Do not use this magnet close to heaters exceeding its safe range. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) are more susceptible to demagnetization under lower heat stress compared to rod magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still large.
*Field value for N-N configuration reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Estimates show sliding force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Hazards (implants) - warnings

A strong magnetic field is a large risk to electronic devices as well as pacemakers. These neodymiums generate a field that prevents correct functioning of digital equipment. Remember: the unseen radiation passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely 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 hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when playing with powerful specimens.

Corrosion warning: 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. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel saturation

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

3. Heat tolerance

*For standard magnets, 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

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 40x15x5 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 11.35 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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 11.35 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. Thanks to the flat surface and high force (approx. 11.35 kg), they are ideal as closers 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash 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 through the thickness (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.

This model is characterized by dimensions 40x15x5 mm, which, at a weight of 22.5 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 11.35 kg (force ~111.37 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of neodymium magnets.

Pros

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

Their power is durable, and after around 10 years it drops only by ~1% (theoretically),
Neodymium magnets remain highly resistant to loss of magnetic properties caused by external field sources,
By applying a lustrous layer of silver, the element presents an nice look,
Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Considering the ability of precise shaping and adaptation to individualized needs, magnetic components can be created in a wide range of geometric configurations, which expands the range of possible applications,
Versatile presence in modern industrial fields – they are commonly used in data components, electromotive mechanisms, medical devices, as well as technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing threads and complex forms in magnets, we propose using casing - magnetic mount.
Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these products are able to complicate diagnosis medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what contributes to it?

Information about lifting capacity is the result of a measurement for the most favorable conditions, taking into account:

on a block made of mild steel, optimally conducting the magnetic field
possessing a thickness of min. 10 mm to avoid saturation
with a plane free of scratches
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Determinants of practical lifting force of a magnet

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

Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.

Pacemakers

For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.

Permanent damage

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.

Beware of splinters

Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.

Dust is flammable

Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Protect data

Do not bring magnets near a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Compass and GPS

Note: neodymium magnets produce a field that confuses precision electronics. Maintain a separation from your mobile, device, and navigation systems.

Pinching danger

Risk of injury: The attraction force is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.

Respect the power

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Adults only
