Strengths and weaknesses of rare earth magnets.
Advantages
- They do not lose strength, even over nearly ten years – the drop in power is only ~1% (based on measurements),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- A magnet with a metallic gold surface has better aesthetics,
- Magnetic induction on the surface of the magnet turns out to be impressive,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the option of free forming and customization to individualized solutions, magnetic components can be modeled in a variety of forms and dimensions, which amplifies use scope,
- Universal use in modern technologies – they serve a role in mass storage devices, electric motors, diagnostic systems, as well as other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to avoid saturation
- with a surface cleaned and smooth
- without any insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Machining danger
Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
Allergy Warning
Some people suffer from a sensitization to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to dermatitis. It is best to wear protective gloves.
Precision electronics
A strong magnetic field disrupts the operation of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.
Material brittleness
NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them cracking into shards.
Medical interference
Patients with a pacemaker must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Do not give to children
NdFeB magnets are not intended for children. Swallowing a few magnets may result in them pinching intestinal walls, which poses a critical condition and requires immediate surgery.
Handling guide
Exercise caution. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can move away.
Data carriers
Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Pinching danger
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
