Grip strength drops drastically per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, paint, dust) significantly reduces the pull force. Magnets work strongest at the point of direct contact; distance drastically cuts the force. See how quickly the pull force plummet, when the product does not touch flatly to the steel surface. When planning the arrangement, avoid unnecessary gaps.

The following data presents the estimated shear load required to initiate the sliding of the magnet vertically along a upright steel wall (assuming standard friction). This value is relative to the distance between the magnet and the metal.

When hanging a holder on a vertical wall (e.g., a car body), it will only hold only approx. 1/5 of its maximum pull force. Gravitational force and a weak degree of grip mean that products slide down faster than they detach. Planning a hanger? Consider that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slip down under a much lighter weight. Using a rubber coating can effectively improve the result.

A thin metal plate is unable to absorb the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To utilize the maximum of this neodymium's potential, you require a sufficiently solid element of metal. The saturation phenomenon means that on thin elements (e.g., thin profiles), the product works worse. We recommend selecting the steel dimension according to the table below.

Classic neodymiums irreversibly lose power past the thermal threshold. Watch out for overheating – heat can irreversibly demagnetize this product. With increasing heat, the magnet's force momentarily decreases. Avoid using this magnet near heat sources exceeding its operating temperature limit. Ignoring the limit will cause permanent loss of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) risk losing magnetic properties sooner than long magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. The setup of two magnets creates a more powerful interaction and a wider radius of performance. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is marginally weaker than the connection force, but still significant.
*Flux density for N-N configuration drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Calculations show friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (electronics) - precautionary measures

Powerful magnet radiation is a large risk to IT equipment as well as pacemakers. These NdFeB products produce a flux that destroys function of digital equipment. Remember: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

100 mm	111.07 km/h (30.85 m/s)	0.74 J

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can cause material chips or dangerous crushing to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when handling with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains just ~20% of its perpendicular strength.

2. Plate thickness effect

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

3. Thermal stability

*For N38 grade, 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) = 0.37

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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.

The ring magnet with a hole MP 10x7/3.5x3 / N38 is created for permanent mounting, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This is a crucial issue when working with model MP 10x7/3.5x3 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. 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. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. This product is dedicated for indoor use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.

The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Aesthetic mounting requires selecting the appropriate head size.

This model is characterized by dimensions Ø10x3 mm and a weight of 1.55 g. The key parameter here is the holding force amounting to approximately 1.88 kg (force ~18.47 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 7/3.5 mm.

The poles are located on the planes with holes, not on the sides of the ring. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Pros and cons of neodymium magnets.

Advantages

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

Their strength remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
Magnets very well protect themselves against demagnetization caused by external fields,
By using a lustrous coating of nickel, the element has an elegant look,
Magnets are characterized by excellent magnetic induction on the outer layer,
Neodymium magnets are characterized by extremely 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 individual creating as well as modifying to individual needs,
Versatile presence in electronics industry – they are utilized in mass storage devices, drive modules, advanced medical instruments, as well as multitasking production systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Cons of neodymium magnets: tips and applications.

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in producing threads and complicated forms in magnets, we propose using casing - magnetic mechanism.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these devices can complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

The load parameter shown refers to the peak performance, obtained under ideal test conditions, specifically:

using a base made of high-permeability steel, acting as a ideal flux conductor
possessing a massiveness of at least 10 mm to avoid saturation
characterized by smoothness
with zero gap (without paint)
during detachment in a direction perpendicular to the mounting surface
at ambient temperature room level

Lifting capacity in real conditions – factors

In practice, the actual lifting capacity is determined by many variables, listed from the most important:

Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Steel thickness – insufficiently thick sheet does not close the flux, causing part of the power to be wasted to the other side.
Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Thermal environment – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.

Warnings

Product not for children

These products are not suitable for play. Eating a few magnets may result in them attracting across intestines, which poses a critical condition and requires immediate surgery.

Cards and drives

Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Life threat

Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Hand protection

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Safe operation

Use magnets with awareness. Their immense force can surprise even professionals. Stay alert and respect their power.

Thermal limits

Control the heat. Exposing the magnet to high heat will destroy its properties and strength.

Sensitization to coating

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop handling magnets and wear gloves.

Combustion hazard

Dust produced during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Precision electronics

GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.

Material brittleness

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