Advantages as well as disadvantages of rare earth magnets.
Benefits
- They retain full power for around ten years – the drop is just ~1% (according to analyses),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a metallic nickel surface has better aesthetics,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- In view of the possibility of accurate molding and adaptation to custom projects, neodymium magnets can be manufactured in a wide range of geometric configurations, which expands the range of possible applications,
- Universal use in innovative solutions – they are utilized in data components, electromotive mechanisms, advanced medical instruments, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions
Cons
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- 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 extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing threads and complicated shapes in magnets, we propose using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- with zero gap (without paint)
- under vertical force vector (90-degree angle)
- at room temperature
Key elements affecting lifting force
- Gap (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
- Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
Bodily injuries
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Skin irritation risks
It is widely known that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and opt for coated magnets.
Do not drill into magnets
Machining of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Medical implants
People with a ICD have to keep an absolute distance from magnets. The magnetism can interfere with the operation of the implant.
Magnet fragility
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Precision electronics
Remember: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your phone, tablet, and GPS.
Operating temperature
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Safe operation
Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.
Electronic hazard
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Swallowing risk
Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
