Pros and cons of rare earth magnets.
Pros
- They retain full power for almost ten years – the loss is just ~1% (based on simulations),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise creating as well as adjusting to specific applications,
- Versatile presence in future technologies – they are commonly used in data components, brushless drives, advanced medical instruments, also modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated forms in magnets, we propose using casing - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products can 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
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a base made of high-permeability steel, serving as a ideal flux conductor
- with a thickness of at least 10 mm
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (rust, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was checked on a smooth steel plate 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 and the plate lowers the holding force.
Precautions when working with neodymium magnets
Do not give to children
Only for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
Maximum temperature
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Life threat
Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Cards and drives
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Allergic reactions
Certain individuals experience a sensitization to Ni, which is the standard coating for neodymium magnets. Extended handling may cause an allergic reaction. We strongly advise use protective gloves.
Conscious usage
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Material brittleness
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Flammability
Powder created during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
GPS Danger
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to prevent breaking the sensors.
Hand protection
Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
