Magnetic force decreases significantly per each millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, varnish, dust) strongly reduces the pull force. Magnets hold most effectively in perfect adhesion; air break weakens the force. Notice how flashily the pull force drop, when the product does not touch flatly to the metal substrate. When designing the mounting, discard redundant distances.

The following data shows the estimated holding capacity necessary to initiate the downward movement of the magnet downwards on a upright steel plate (assuming typical friction coefficient). This parameter depends on the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MP 5x2.7/1.2x5 C / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.50 LBS 225.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 LBS 150.0 g / 1.5 N

When hanging a magnet on a vertical surface (e.g., a car body), it you can count on just approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip cause that products slide down easier than they detach. Designing a vertical fastening? Remember that the shear force is significantly lower than the maximum static pull force. On a painted metal, the element will slip down under a much lighter cargo. Utilizing a rubberized pad can effectively increase the grip.

A thin metal plate cannot take in the entire magnetic field, which wastes potential of the holder. If you attach a powerful product to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To achieve the maximum of this magnet's potential, you need a suitably thick element of metal. The saturation phenomenon means that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel thickness based on the following data.

Standard neodymium magnets lose strength above the temperature limit. Watch out for overheating – excessive heat can irreversibly demagnetize this product. With every degree above norm, the neodymium's power momentarily lowers. Refrain from using this product close to heaters higher than its working range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet setup. Such a system of two magnets creates a more powerful interaction and a further horizon of action. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is extreme. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
* Calculations refer to shear force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to electronic devices and pacemakers. These NdFeB products generate a field that disrupts operation of digital equipment. Be aware: the unseen radiation acts through matter and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can cause material chips or injury to skin. Hold the magnet firmly during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

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

2. Steel thickness impact

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.83

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.

The ring magnet with a hole MP 5x2.7/1.2x5 C / N38 is created for permanent mounting, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. This product with a force of 0.75 kg works great as a cabinet closure, speaker holder, or mounting element in devices.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a flexible washer 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 can be damaged when tightening the screw, which will become a corrosion focus. This product is dedicated for inside building use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

The inner hole diameter determines the maximum size of the mounting element. 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 (5 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø5x5 mm and a weight of 0.69 g. The key parameter here is the holding force amounting to approximately 0.75 kg (force ~7.31 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 2.7/1.2 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:

Their strength is maintained, and after around ten years it decreases only by ~1% (theoretically),
They feature excellent resistance to weakening of magnetic properties as a result of external fields,
In other words, due to the metallic layer of nickel, the element is aesthetically pleasing,
The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
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 designing and the capacity to adapt to complex applications,
Universal use in high-tech industry – they serve a role in magnetic memories, electric motors, precision medical tools, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions

Disadvantages

Cons of neodymium magnets and proposals for their use:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises 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 power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of producing nuts in the magnet and complex shapes - preferred is casing - magnetic holder.
Possible danger resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

The declared magnet strength concerns the peak performance, recorded under ideal test conditions, meaning:

with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
whose thickness equals approx. 10 mm
with a plane perfectly flat
under conditions of gap-free contact (surface-to-surface)
under vertical application of breakaway force (90-degree angle)
at conditions approx. 20°C

Key elements affecting lifting force

Effective lifting capacity is affected by working environment parameters, such as (from most important):

Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Steel thickness – too thin plate causes magnetic saturation, causing part of the power to be wasted into the air.
Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Nickel coating and allergies

Certain individuals have a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling may cause dermatitis. It is best to wear protective gloves.

Finger safety

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Pacemakers

For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Fragile material

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.

Do not underestimate power

Use magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their power.

Electronic devices

Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.

GPS Danger

Remember: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your mobile, device, and navigation systems.

Flammability

Powder created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

No play value

Only for adults. Small elements pose a choking risk, causing severe trauma. Keep away from children and animals.

Do not overheat magnets

Keep cool. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
