Advantages as well as disadvantages of rare earth magnets.
Benefits
- They retain attractive force for around 10 years – the drop is just ~1% (in theory),
- They maintain their magnetic properties even under external field action,
- Thanks to the smooth finish, the coating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnets exhibit extremely high magnetic induction on the active area,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise machining as well as modifying to precise applications,
- Huge importance in modern technologies – they find application in computer drives, electromotive mechanisms, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Limitations
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend 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
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these devices are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a plate made of mild steel, acting as a ideal flux conductor
- with a thickness of at least 10 mm
- with a plane perfectly flat
- under conditions of no distance (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Gap (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Handling guide
Exercise caution. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
Electronic devices
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Dust is flammable
Dust created during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Impact on smartphones
Be aware: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Keep away from children
These products are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.
Thermal limits
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Health Danger
Patients with a ICD have to maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.
Allergy Warning
Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and opt for versions in plastic housing.
Shattering risk
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
