1. Shear force
*Warning: On a vertical surface, the magnet holds only approx. 20-30% of its max power.
2. Steel thickness impact
*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.
3. Temperature resistance
*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) = 1.55
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.

Advantages and disadvantages of rare earth magnets.
Pros
- Their strength is durable, and after around 10 years it drops only by ~1% (according to research),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external interference,
- By using a reflective layer of silver, the element acquires an aesthetic look,
- The surface of neodymium magnets generates a strong 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...
- Possibility of individual forming and adjusting to specific requirements,
- Key role in advanced technology sectors – they serve a role in hard drives, brushless drives, medical devices, also multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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
- 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.
- We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is relatively high,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a plate made of mild steel, functioning as a circuit closing element
- with a cross-section no less than 10 mm
- with an polished touching surface
- under conditions of no distance (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at temperature room level
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Crushing force
Mind your fingers. Two large magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Magnets are brittle
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Danger to the youngest
Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are very dangerous.
Implant safety
Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Heat warning
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Dust explosion hazard
Dust generated during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Handling guide
Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can react.
Cards and drives
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Precision electronics
A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to prevent damaging the sensors.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.
