1. Wall mount (shear)
*Note: On a vertical surface, the magnet retains just approx. 20-30% of its max power.
2. Steel thickness impact
*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.
3. Heat tolerance
*For N38 material, the safety limit is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.49
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 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.

Strengths as well as weaknesses of neodymium magnets.
Advantages
- They do not lose strength, even after approximately 10 years – the decrease in strength is only ~1% (according to tests),
- They maintain their magnetic properties even under close interference source,
- A magnet with a metallic gold surface has better aesthetics,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Thanks to the ability of precise forming and customization to specialized requirements, neodymium magnets can be manufactured in a broad palette of forms and dimensions, which increases their versatility,
- Fundamental importance in high-tech industry – they are utilized in computer drives, electric drive systems, medical equipment, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their force 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using cover - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a block made of mild steel, optimally conducting the magnetic flux
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- with zero gap (without impurities)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Key elements affecting lifting force
- Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the flux to be wasted into the air.
- Material type – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safe handling of neodymium magnets
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, cease handling magnets and use protective gear.
Medical interference
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Fragile material
NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them cracking into small pieces.
Electronic devices
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
This is not a toy
Absolutely store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.
GPS Danger
Note: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and GPS.
Combustion hazard
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Demagnetization risk
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Bone fractures
Large magnets can smash fingers in a fraction of a second. Never put your hand betwixt two strong magnets.
Conscious usage
Handle magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and respect their power.
