1. Wall mount (shear)
*Warning: On a vertical surface, the magnet holds just ~20% of its nominal pull.
2. Steel thickness impact
*Thin steel (e.g. computer case) significantly limits 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 Pc (Permeance Coefficient) = 0.27
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 Pc (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 Pc 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.

Pros and cons of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets are distinguished by extremely resistant to demagnetization caused by external magnetic fields,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They show high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- Thanks to versatility in constructing and the ability to modify to unusual requirements,
- Wide application in modern technologies – they are utilized in hard drives, motor assemblies, medical equipment, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of making threads in the magnet and complicated forms - recommended is a housing - mounting mechanism.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- whose thickness equals approx. 10 mm
- with an ground touching surface
- with direct contact (without paint)
- under vertical force vector (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be escaped to the other side.
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast 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 decreases the holding force.
Precautions when working with neodymium magnets
Dust explosion hazard
Dust generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Phone sensors
GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
ICD Warning
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Crushing force
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Caution required
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Warning for allergy sufferers
Certain individuals have a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in a rash. We recommend use protective gloves.
Permanent damage
Do not overheat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Beware of splinters
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Choking Hazard
Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Keep away from kids and pets.
Electronic hazard
Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
