Grip strength decreases drastically per each millimeter of spacing. Keep in mind that even the smallest gap (e.g., contamination, paint, dust) strongly weakens the grip. Neodymiums operate most effectively during direct contact; gap kills the force. Observe how rapidly the load capacity plummet, when the product does not touch directly to the steel surface. When designing the arrangement, discard unnecessary gaps.

The table below indicates the theoretical shear load sufficient to cause the shifting of the magnet downwards along a vertical metal surface (considering standard friction). This parameter depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	17.60 kg / 38.80 LBS 17601.0 g / 172.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	11.73 kg / 25.87 LBS 11734.0 g / 115.1 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	29.34 kg / 64.67 LBS 29335.0 g / 287.8 N

When mounting a magnet on a vertical plane (e.g., a board), it will maintain only about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that products slip faster than they detach. Want to create a hanger? Note that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the magnet will slip down under a much lighter weight. Utilizing a rubberized coating can drastically improve the result.

A thin sheet is unable to focus the full magnetic flux, which squanders power of the holder. Should you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To utilize full efficiency of this magnet's potential, you need a suitably thick backing of steel. The material oversaturation causes that on thin elements (e.g., car bodies), the product works worse. We suggest choosing the steel cross-section from these parameters.

Classic neodymiums irreversibly lose parameters above the temperature limit. Avoid high temperatures – heat can permanently destroy this magnet. With increasing heat, the magnet's capacity momentarily decreases. Do not use this product in hot environments exceeding its safe range. Exceeding the critical threshold will result in permanent loss of magnetism.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and steel setup. Such a system of two magnets creates a more powerful interaction and a larger range of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is massive. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Attention: Figures apply to shear force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a serious hazard to electronics as well as pacemakers. These magnets produce a field that disrupts operation of digital equipment. Be aware: the unseen radiation acts through matter and housings. Exceptional care must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a violent impact against metal risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. 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 metal. A collision at high speed means shattering of the neodymium. Use safety goggles when handling with powerful specimens.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains only a fraction of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Power loss vs temp

*For N38 material, 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) = 0.64

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Mounting is clean and reversible, unlike gluing. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure will cause the ring to crack. It's a good idea to use a rubber spacer under the screw head, which will cushion the stresses. Remember: cracking during assembly results from material properties, not a product defect.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for indoor use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 42 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Always check that the screw head is not larger than the outer diameter of the magnet (62 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø62x25 mm and a weight of 306.31 g. The key parameter here is the lifting capacity amounting to approximately 58.67 kg (force ~575.60 N). The mounting hole diameter is precisely 42 mm.

The poles are located on the planes with holes, not on the sides of the ring. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Pros and cons of rare earth magnets.

Advantages

Besides their exceptional field intensity, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
Neodymium magnets are distinguished by highly resistant to loss of magnetic properties caused by magnetic disturbances,
The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Possibility of individual shaping as well as modifying to individual applications,
Fundamental importance in electronics industry – they find application in data components, electric drive systems, medical devices, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
NdFeB 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
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - 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 magnets are able to complicate diagnosis medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum lifting force for a neodymium magnet – what contributes to it?

Breakaway force was determined for the most favorable conditions, assuming:

using a sheet made of mild steel, acting as a circuit closing element
whose transverse dimension is min. 10 mm
with an ground touching surface
without any insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
in neutral thermal conditions

Practical aspects of lifting capacity – factors

In practice, the actual holding force depends on many variables, listed from the most important:

Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Direction of force – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Plate material – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.

Warnings

Nickel allergy

Certain individuals experience a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling might lead to dermatitis. We recommend use protective gloves.

Do not overheat magnets

Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and strength.

Impact on smartphones

Remember: neodymium magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, tablet, and GPS.

Beware of splinters

Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets will cause them shattering into shards.

Warning for heart patients

Individuals with a ICD must maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the implant.

Adults only

Neodymium magnets are not intended for children. Eating multiple magnets can lead to them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.

Caution required

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.

Crushing force

Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Dust is flammable

Dust created during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Safe distance

Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Security! More info about hazards in the article: Safety of working with magnets.
