Pros as well as cons of neodymium magnets.
Benefits
- They retain full power for almost 10 years – the loss is just ~1% (in theory),
- They are extremely resistant to demagnetization induced by external disturbances,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets are distinguished by impressive magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in designing and the ability to customize to unusual requirements,
- Wide application in innovative solutions – they serve a role in HDD drives, electromotive mechanisms, medical equipment, and technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets lose their power 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complicated forms in magnets, we propose using casing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- on a plate made of mild steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- characterized by lack of roughness
- with direct contact (no impurities)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Angle of force application – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Hand protection
Large magnets can break fingers in a fraction of a second. Do not put your hand between two strong magnets.
Electronic devices
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Skin irritation risks
Certain individuals experience a contact allergy to Ni, which is the standard coating for NdFeB magnets. Extended handling may cause dermatitis. It is best to use safety gloves.
Flammability
Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
GPS and phone interference
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
Danger to the youngest
NdFeB magnets are not suitable for play. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.
Beware of splinters
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Danger to pacemakers
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Power loss in heat
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Do not underestimate power
Be careful. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can react.
