Magnetic force weakens drastically with every mm of spacing. Note that even the smallest gap (e.g., contamination, varnish, rust) noticeably weakens the grip. Magnetic products hold optimally during direct contact; gap nullifies the power. Notice how quickly the parameters fall, when the product does not adhere flatly to the steel surface. When designing the mounting, eliminate additional spacers.

The following data defines the approximate shear load sufficient to start the slippage of the magnet down along a vertical metal surface (assuming typical friction coefficient). This value depends on the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MPL 50x20x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	12.65 kg / 27.90 pounds 12654.0 g / 124.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	8.44 kg / 18.60 pounds 8436.0 g / 82.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	4.22 kg / 9.30 pounds 4218.0 g / 41.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	21.09 kg / 46.50 pounds 21090.0 g / 206.9 N

When hanging a element on a upright wall (e.g., a board), it will maintain barely approx. 1/5 of its nominal power. Gravity and a weak degree of grip mean that magnets slide down easier than they detach. Designing a vertical fastening? Remember that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the element will slip down under a noticeably lighter weight. Utilizing a rubberized coating can drastically raise the stability.

A thin sheet is unable to absorb the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To squeeze 100% of this magnet's power, you need a suitably thick backing of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet holds weaker. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly damage this product. With every degree above norm, the neodymium's force temporarily lowers. Avoid using this product near heat sources exceeding its working range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. Red status in the table indicates permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a wider radius of operation. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the collision energy is extreme. The levitation is slightly lower than the connection force, but still large.
*Field value for N-N configuration drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
Note: Estimates refer to friction force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a real danger to IT equipment as well as pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the unseen radiation acts through matter and glass. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can cause material chips or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when working with powerful specimens.

Corrosion 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains only a fraction of its max power.

2. Steel thickness impact

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

3. Thermal stability

*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) = 0.63

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 50x20x20 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 42.18 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting 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. To separate the MPL 50x20x20 / 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.

For mounting flat magnets MPL 50x20x20 / 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 50x20x20 / N38 model is magnetized through the thickness (dimension 20 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 (50x20 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 50x20x20 mm, which, at a weight of 150 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 42.18 kg (force ~413.81 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros and cons of rare earth magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They show high resistance to demagnetization induced by presence of other magnetic fields,
In other words, due to the metallic surface of silver, the element looks attractive,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
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...
Possibility of precise creating as well as optimizing to specific requirements,
Significant place in high-tech industry – they find application in hard drives, electromotive mechanisms, advanced medical instruments, also industrial machines.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Disadvantages

Disadvantages of neodymium magnets:

At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We suggest casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Detachment force of the magnet in optimal conditions – what affects it?

Holding force of 42.18 kg is a theoretical maximum value conducted under standard conditions:

using a sheet made of low-carbon steel, serving as a ideal flux conductor
with a cross-section of at least 10 mm
with an ground contact surface
with total lack of distance (without impurities)
for force applied at a right angle (in the magnet axis)
in stable room temperature

Practical aspects of lifting capacity – factors

It is worth knowing that the magnet holding may be lower depending on the following factors, in order of importance:

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Temperature – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with neodymium magnets

Material brittleness

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Medical interference

People with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.

Avoid contact if allergic

It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or select versions in plastic housing.

Compass and GPS

Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Do not underestimate power

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Protect data

Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Do not give to children

Adult use only. Small elements pose a choking risk, causing severe trauma. Keep out of reach of kids and pets.

Crushing risk

Risk of injury: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.

Mechanical processing

Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Operating temperature

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
