Pros and cons of neodymium magnets.
Strengths
- They retain magnetic properties for almost 10 years – the loss is just ~1% (based on simulations),
- They are resistant to demagnetization induced by external field influence,
- By using a shiny coating of gold, the element has an proper look,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in forming and the ability to customize to client solutions,
- Huge importance in advanced technology sectors – they are commonly used in HDD drives, drive modules, precision medical tools, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- At very strong impacts they can break, therefore we recommend 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 weakening of power (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 rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing threads in the magnet and complex shapes - preferred is a housing - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- with a cross-section of at least 10 mm
- with an ideally smooth touching surface
- with total lack of distance (without paint)
- during pulling in a direction perpendicular to the mounting surface
- at room temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safe handling of neodymium magnets
Bodily injuries
Large magnets can break fingers instantly. Never place your hand between two strong magnets.
Threat to electronics
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Sensitization to coating
It is widely known that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or choose encased magnets.
Mechanical processing
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Heat warning
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Beware of splinters
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Impact on smartphones
Remember: neodymium magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
Keep away from children
Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of children and animals.
Medical interference
Patients with a ICD should keep an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Caution required
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
