Pros and cons of rare earth magnets.
Advantages
- They do not lose magnetism, even over around ten years – the drop in strength is only ~1% (theoretically),
- They maintain their magnetic properties even under close interference source,
- By using a smooth layer of nickel, the element presents an aesthetic look,
- They feature high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of custom shaping and adjusting to specific requirements,
- Wide application in advanced technology sectors – they find application in hard drives, drive modules, medical devices, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using casing - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- using a base made of mild steel, acting as a magnetic yoke
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
H&S for magnets
Magnetic media
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Adults only
Always store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Fire warning
Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Crushing force
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Implant safety
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Metal Allergy
Some people have a contact allergy to Ni, which is the standard coating for neodymium magnets. Extended handling may cause a rash. We strongly advise wear safety gloves.
Heat warning
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Immense force
Use magnets with awareness. Their powerful strength can shock even professionals. Stay alert and respect their force.
Fragile material
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them shattering into small pieces.
Phone sensors
Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
