Advantages and disadvantages of rare earth magnets.
Benefits
- Their power remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets are distinguished by extremely resistant to demagnetization caused by magnetic disturbances,
- Thanks to the smooth finish, the surface of nickel, gold, or silver gives an clean appearance,
- Magnets have very high magnetic induction on the surface,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of precise modeling and adjusting to defined conditions,
- Huge importance in modern industrial fields – they are used in data components, electric motors, diagnostic systems, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in miniature devices
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making threads in the magnet and complex forms - preferred is cover - mounting mechanism.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of low-carbon steel, acting as a magnetic yoke
- whose transverse dimension is min. 10 mm
- with a surface cleaned and smooth
- without any air gap between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Health Danger
Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Fire warning
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Magnetic media
Do not bring magnets near a wallet, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Material brittleness
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Compass and GPS
An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets near a device to prevent breaking the sensors.
Permanent damage
Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Pinching danger
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Metal Allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or opt for coated magnets.
Do not give to children
Absolutely keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.
Powerful field
Use magnets consciously. Their immense force can shock even professionals. Plan your moves and do not underestimate their power.
