Grip strength decreases significantly with every subsequent millimeter of gap. Remember that even a very thin break (e.g., dirt, paint, dust) significantly reduces the pull force. Neodymiums hold strongest in perfect adhesion; distance nullifies the force. Analyze how rapidly the parameters drop, when the magnet does not touch flatly to the metal substrate. When designing the arrangement, eliminate unnecessary gaps.

This section presents the estimated holding capacity sufficient to cause the slippage of the magnet vertically along a upright steel plate (assuming standard friction coefficient). This parameter is relative to the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 5x5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.23 kg / 0.51 lbs 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 lbs 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 lbs 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 lbs 385.0 g / 3.8 N

When mounting a holder on a vertical plane (e.g., a fridge), it will only hold only about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that holders move down easier than they pop off the substrate. Planning a vertical fastening? Remember that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the element will slide down under a noticeably lighter load. Application of an anti-slip layer can effectively improve the result.

12 mm	100%	0.77 kg / 1.70 lbs 770.0 g / 7.6 N

A too thin steel is not enough to take in the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's power, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder works worse. We advise picking the steel cross-section from these parameters.

Ordinary NdFeB products change their properties power past the thermal threshold. Watch out for overheating – high temperature can permanently demagnetize this product. With every degree above norm, the magnet's force briefly decreases. Avoid using this product close to heaters exceeding its safe range. Exceeding the critical threshold will lead to destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) are more susceptible to demagnetization under lower heat stress than long magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a wider radius of operation. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the connection force, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Estimates demonstrate sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a real danger to electronic devices as well as pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

100 mm	143.56 km/h (39.88 m/s)	0.30 J

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or painful pinches to skin. Be sure to control the product 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. Use safety goggles when playing with large magnets.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly weakens 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) = 0.46

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 5x5x2 mm and a weight of 0.38 g, guarantees premium class connection. As a magnetic bar with high power (approx. 0.77 kg), this product is available off-the-shelf 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 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. Watch your fingers! Magnets with a force of 0.77 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 5x5x2 / 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 5x5x2 / N38, we recommend utilizing 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 5x5x2 / N38 model is magnetized axially (dimension 2 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 5x5x2 mm, which, at a weight of 0.38 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 0.77 kg (force ~7.57 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 rare earth magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
They show high resistance to demagnetization induced by presence of other magnetic fields,
Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Thanks to flexibility in forming and the ability to modify to client solutions,
Key role in future technologies – they find application in data components, drive modules, medical devices, and other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of making nuts in the magnet and complicated shapes - preferred is casing - magnet mounting.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
With budget limitations the cost of neodymium magnets is a challenge,

Pull force analysis

Best holding force of the magnet in ideal parameters – what it depends on?

The declared magnet strength refers to the maximum value, recorded under optimal environment, namely:

with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
possessing a thickness of minimum 10 mm to ensure full flux closure
with an polished touching surface
with total lack of distance (no impurities)
for force acting at a right angle (pull-off, not shear)
at conditions approx. 20°C

Practical aspects of lifting capacity – factors

It is worth knowing that the magnet holding may be lower influenced by the following factors, starting with the most relevant:

Gap (betwixt the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.

Precautions when working with neodymium magnets

Choking Hazard

Absolutely keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are life-threatening.

Nickel coating and allergies

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.

Eye protection

NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them shattering into shards.

Electronic hazard

Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.

Impact on smartphones

An intense magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.

Hand protection

Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.

Respect the power

Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.

Warning for heart patients

Warning for patients: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.

Do not drill into magnets

Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Power loss in heat

Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).

Warning! More info about risks in the article: Magnet Safety Guide.
