Pros as well as cons of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
- Magnets very well defend themselves against demagnetization caused by external fields,
- By covering with a decorative coating of silver, the element presents an proper look,
- Magnets are characterized by very high magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of precise modeling as well as modifying to complex applications,
- Significant place in modern industrial fields – they find application in computer drives, electric drive systems, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in miniature devices
Limitations
- At very 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.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of making threads in the magnet and complicated forms - recommended is cover - mounting mechanism.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- whose thickness is min. 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Clearance – the presence of any layer (rust, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Safe handling of neodymium magnets
Caution required
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Combustion hazard
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Do not give to children
Only for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of children and animals.
Heat sensitivity
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Metal Allergy
Some people experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to dermatitis. We strongly advise wear protective gloves.
ICD Warning
Individuals with a ICD should maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Protective goggles
NdFeB magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them breaking into small pieces.
Compass and GPS
GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Hand protection
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Electronic devices
Do not bring magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
