Grip strength drops sharply with every mm of distance. Remember that even a microscopic distance (e.g., dirt, paint, rust) noticeably weakens the grip. Neodymiums operate most effectively in perfect adhesion; distance nullifies the power. Observe how flashily the load capacity drop, when the product does not adhere flatly to the metal substrate. When designing the assembly, avoid unnecessary gaps.

The table below calculates the approximate holding capacity sufficient to cause the shifting of the magnet down along a vertical steel wall (considering typical friction coefficient). This parameter is a function of the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MPL 7x7x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.48 kg / 1.06 pounds 480.0 g / 4.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.32 kg / 0.71 pounds 320.0 g / 3.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.16 kg / 0.35 pounds 160.0 g / 1.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.80 kg / 1.76 pounds 800.0 g / 7.8 N

When hanging a holder on a vertical surface (e.g., a car body), it will only hold barely about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that products slip easier than they pop off the substrate. Designing a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a noticeably lighter cargo. Utilizing a rubberized coating can drastically increase the grip.

12 mm	100%	1.60 kg / 3.53 pounds 1600.0 g / 15.7 N

A thin metal plate is unable to take in the full magnetic flux, which wastes potential of the holder. If you attach a powerful product to a weak sheet, the field will pass right through and the attraction force will be weaker. To utilize full efficiency of this magnet's potential, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We suggest choosing the steel dimension according to the table below.

Ordinary NdFeB products change their properties power past the thermal threshold. Avoid high temperatures – excessive heat can permanently destroy this magnet. With increasing heat, the neodymium's power momentarily lowers. Do not use this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will cause irreversible degradation of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a wider radius than a neodymium and metal combination. The setup of two magnets generates a stronger field and a larger range of action. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the impact force is extreme. The levitation is marginally weaker than the attraction, but still significant.
*Flux density in repulsion mode drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
* Figures refer to shear force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to IT equipment and pacemakers. These neodymiums generate a flux that disrupts operation of digital equipment. Notice: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MPL 7x7x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	38.51 km/h (10.70 m/s)	0.06 J
30 mm	66.62 km/h (18.51 m/s)	0.19 J
50 mm	86.01 km/h (23.89 m/s)	0.31 J
100 mm	121.63 km/h (33.79 m/s)	0.63 J

Magnetic elements are very brittle – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can cause material chips or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when working with powerful specimens.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet holds merely a fraction of its perpendicular strength.

2. Plate thickness effect

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

3. Heat tolerance

*For N38 grade, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.48

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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 7x7x3 mm and a weight of 1.1 g, guarantees premium class connection. As a block magnet with high power (approx. 1.60 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures 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 7x7x3 / 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.

Plate magnets MPL 7x7x3 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 1.60 kg), they are ideal as hidden locks 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 7x7x3 / N38, it is best to use 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. 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 7x7x3 / N38 model is magnetized axially (dimension 3 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 (7x7 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 7x7x3 mm, which, at a weight of 1.1 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 1.60 kg (force ~15.70 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of neodymium magnets.

Pros

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

They retain full power for almost 10 years – the loss is just ~1% (according to analyses),
Neodymium magnets are extremely resistant to demagnetization caused by external interference,
Thanks to the shiny finish, the plating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to freedom in shaping and the ability to customize to complex applications,
Universal use in high-tech industry – they serve a role in computer drives, drive modules, advanced medical instruments, also modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these products can complicate diagnosis medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what affects it?

Breakaway force is the result of a measurement for the most favorable conditions, including:

with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
possessing a massiveness of at least 10 mm to avoid saturation
characterized by even structure
with direct contact (without impurities)
under vertical force direction (90-degree angle)
at ambient temperature room level

What influences lifting capacity in practice

It is worth knowing that the working load may be lower subject to elements below, starting with the most relevant:

Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

H&S for magnets

Nickel allergy

Studies show that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and select versions in plastic housing.

Shattering risk

Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them breaking into shards.

Phone sensors

Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Keep a separation from your mobile, tablet, and GPS.

Flammability

Machining of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Do not overheat magnets

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

Bone fractures

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

Health Danger

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Magnetic media

Device Safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Safe operation

Use magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their power.

Swallowing risk

Absolutely keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.
