Pros as well as cons of neodymium magnets.
Advantages
- They do not lose strength, even over nearly 10 years – the drop in strength is only ~1% (according to tests),
- Magnets very well protect themselves against demagnetization caused by external fields,
- Thanks to the shiny finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Considering the ability of flexible forming and adaptation to unique projects, neodymium magnets can be modeled in a variety of shapes and sizes, which amplifies use scope,
- Huge importance in modern technologies – they serve a role in magnetic memories, electromotive mechanisms, precision medical tools, 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
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose their strength 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 rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Highest magnetic holding force – what it depends on?
- on a base made of structural steel, optimally conducting the magnetic field
- whose thickness reaches at least 10 mm
- with an ground touching surface
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Beware of splinters
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Dust explosion hazard
Powder generated during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Handling rules
Handle magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.
Electronic devices
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Thermal limits
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Crushing force
Large magnets can crush fingers instantly. Never put your hand betwixt two strong magnets.
Magnetic interference
Remember: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, device, and GPS.
Health Danger
People with a ICD must maintain an absolute distance from magnets. The magnetism can stop the operation of the life-saving device.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease handling magnets and use protective gear.
Do not give to children
Only for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of children and animals.
