Pros as well as cons of neodymium magnets.
Pros
- They retain full power for around ten years – the loss is just ~1% (based on simulations),
- They maintain their magnetic properties even under external field action,
- In other words, due to the metallic finish of nickel, the element is aesthetically pleasing,
- Magnets are characterized by huge magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of detailed modeling and adjusting to individual needs,
- Versatile presence in innovative solutions – they are used in data components, electric motors, advanced medical instruments, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as 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 during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making nuts in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products are able to complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an polished touching surface
- without any clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces capacity rapidly (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 surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate causes magnetic saturation, causing part of the power to be wasted to the other side.
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Danger to pacemakers
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Swallowing risk
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep away from children and animals.
Permanent damage
Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Mechanical processing
Dust created during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Handling rules
Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.
Nickel allergy
Studies show that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact or opt for encased magnets.
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them breaking into shards.
Protect data
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Pinching danger
Large magnets can crush fingers instantly. Do not put your hand betwixt two attracting surfaces.
Magnetic interference
Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.
