1. Sliding resistance
*Note: On a vertical surface, the magnet retains just approx. 20-30% of its nominal pull.
2. Plate thickness effect
*Thin steel (e.g. computer case) drastically reduces the holding force.
3. Power loss vs temp
*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) = 0.74
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.

Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for around 10 years – the loss is just ~1% (based on simulations),
- Neodymium magnets prove to be remarkably resistant to demagnetization caused by magnetic disturbances,
- By applying a lustrous coating of nickel, the element has an aesthetic look,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in designing and the ability to customize to complex applications,
- Key role in high-tech industry – they serve a role in data components, electric drive systems, medical devices, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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 magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in producing threads and complex shapes in magnets, we propose using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these products can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- using a plate made of mild steel, functioning as a magnetic yoke
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Product not for children
Strictly keep magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.
Demagnetization risk
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Metal Allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and opt for encased magnets.
Warning for heart patients
Warning for patients: Powerful magnets affect medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Crushing risk
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Threat to electronics
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Threat to navigation
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
Mechanical processing
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Material brittleness
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
