Pros as well as cons of rare earth magnets.
Strengths
- They do not lose magnetism, even over approximately ten years – the reduction in power is only ~1% (according to tests),
- Neodymium magnets are remarkably resistant to demagnetization caused by external field sources,
- A magnet with a smooth nickel surface has better aesthetics,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact modeling as well as adjusting to atypical needs,
- Huge importance in modern technologies – they serve a role in magnetic memories, electric motors, medical devices, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- NdFeB 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 extremely resistant to heat
- 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
- Limited possibility of making nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- whose thickness reaches at least 10 mm
- with a surface free of scratches
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Warnings
Serious injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
Warning for heart patients
Individuals with a heart stimulator should keep an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Safe distance
Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Do not give to children
Neodymium magnets are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets will cause them breaking into shards.
Dust explosion hazard
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Thermal limits
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Sensitization to coating
Certain individuals have a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Frequent touching can result in a rash. We suggest use safety gloves.
Phone sensors
A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a device to avoid damaging the sensors.
Caution required
Be careful. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can react.
