Pros and cons of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They maintain their magnetic properties even under close interference source,
- Thanks to the glossy finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Possibility of accurate machining as well as adjusting to concrete conditions,
- Huge importance in innovative solutions – they are utilized in magnetic memories, drive modules, diagnostic systems, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its 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
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these products can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- using a plate made of mild steel, functioning as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- without any insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of any layer (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be lost to the other side.
- Plate material – low-carbon steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Avoid contact if allergic
Some people suffer from a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to an allergic reaction. It is best to wear safety gloves.
Eye protection
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Compass and GPS
Note: neodymium magnets generate a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.
Thermal limits
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Cards and drives
Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Life threat
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Crushing risk
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Conscious usage
Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.
This is not a toy
NdFeB magnets are not intended for children. Eating several magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates urgent medical intervention.
