1. Vertical hold
*Warning: On a vertical surface, the magnet retains only a fraction of its max power.
2. Steel thickness impact
*Thin metal sheet (e.g. 0.5mm PC case) severely weakens the holding force.
3. Heat tolerance
*For standard magnets, the max working temp is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.26
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 as well as disadvantages of rare earth magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They are resistant to demagnetization induced by external field influence,
- In other words, due to the metallic finish of nickel, the element is aesthetically pleasing,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Due to the potential of precise molding and customization to specialized projects, neodymium magnets can be manufactured in a broad palette of forms and dimensions, which amplifies use scope,
- Wide application in modern industrial fields – they are utilized in HDD drives, brushless drives, advanced medical instruments, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Cons
- At very strong impacts they can break, therefore we advise placing them in steel cases. 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 drop of power (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.
- Limited possibility of creating threads in the magnet and complex forms - preferred is a housing - magnet mounting.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these magnets are able to complicate diagnosis 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 magnetic pulling force – what contributes to it?
- using a base made of high-permeability steel, serving as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick steel does not close the flux, causing part of the power to be wasted into the air.
- Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
No play value
NdFeB magnets are not suitable for play. Eating several magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.
Operating temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Bodily injuries
Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Fire warning
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them shattering into small pieces.
Electronic devices
Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Threat to navigation
Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Do not underestimate power
Handle magnets with awareness. Their huge power can shock even professionals. Be vigilant and do not underestimate their force.
Medical interference
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
