Grip strength decreases drastically with every subsequent millimeter of gap. Remember that even a very thin break (e.g., contamination, paint, veneer) strongly weakens the grip. Magnets hold strongest during direct contact; air break kills the force. Notice how flashily the load capacity drop, when the product does not touch tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

This section shows the estimated holding capacity required to initiate the sliding of the magnet downwards on a upright metal surface (assuming typical friction). The holding force depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 20x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.85 kg / 4.07 lbs 1845.0 g / 18.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.23 kg / 2.71 lbs 1230.0 g / 12.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.62 kg / 1.36 lbs 615.0 g / 6.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.08 kg / 6.78 lbs 3075.0 g / 30.2 N

When placing a holder on a vertical plane (e.g., a car body), it you can count on only approx. 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient mean that holders move down faster than they detach. Want to create a vertical fastening? Note that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will slide down under a noticeably lighter cargo. Using a rubber layer can drastically raise the stability.

A thin sheet is unable to focus the entire magnetic field, which wastes potential of the holder. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To utilize 100% of this neodymium's potential, you require a sufficiently solid backing of metal. The material oversaturation means that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets lose parameters above the temperature limit. Watch out for overheating – heat can irreversibly destroy this product. With every degree above norm, the magnet's force momentarily decreases. Avoid using this magnet close to ovens exceeding its operating temperature limit. Too high temperature will result in irreversible degradation of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than long magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. Such a system of two magnets produces a massive flux and a further horizon of performance. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The repulsion force is marginally weaker than the connection force, but still significant.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
* Estimates show sliding force of dual same magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a large risk to electronics and medical implants. These NdFeB products produce a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when handling with powerful specimens.

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

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Thermal stability

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.42

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 plate magnet made of NdFeB material, which, with dimensions of 20x10x5 mm and a weight of 7.5 g, guarantees the highest quality connection. As a block magnet with high power (approx. 6.15 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.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 20x10x5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 20x10x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 6.15 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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).

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (20x10 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 10 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 6.15 kg (force ~60.31 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of neodymium magnets.

Strengths

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

They do not lose magnetism, even over nearly 10 years – the reduction in lifting capacity is only ~1% (theoretically),
Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Possibility of exact modeling as well as optimizing to complex applications,
Fundamental importance in modern technologies – they are utilized in HDD drives, brushless drives, precision medical tools, as well as other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Disadvantages

What to avoid - cons of neodymium magnets: weaknesses and usage proposals

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
We suggest casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

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

The force parameter is a result of laboratory testing executed under specific, ideal conditions:

with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
whose transverse dimension equals approx. 10 mm
characterized by smoothness
under conditions of no distance (metal-to-metal)
under perpendicular force vector (90-degree angle)
at conditions approx. 20°C

What influences lifting capacity in practice

Real force impacted by working environment parameters, such as (from most important):

Distance (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
Steel thickness – too thin steel does not accept the full field, causing part of the flux to be wasted into the air.
Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.

H&S for magnets

Do not overheat magnets

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.

Impact on smartphones

Remember: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Data carriers

Do not bring magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Danger to pacemakers

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Risk of cracking

Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.

Fire warning

Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Safe operation

Be careful. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can react.

Choking Hazard

Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from children and animals.

Allergic reactions

Some people experience a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching can result in an allergic reaction. It is best to use safety gloves.

Bone fractures

Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
