Pros and cons of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external field sources,
- Thanks to the smooth finish, the plating of nickel, gold-plated, or silver gives an elegant appearance,
- They show high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of accurate machining and adapting to defined requirements,
- Versatile presence in modern industrial fields – they are utilized in hard drives, electric drive systems, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in small systems
Limitations
- They are prone to damage upon too strong 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
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these devices can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- with an ground touching surface
- without any clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined 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 minimal clearance between the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Eye protection
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
Compass and GPS
Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
Fire warning
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Adults only
Always store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.
Serious injuries
Risk of injury: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Medical interference
Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Data carriers
Do not bring magnets close to a purse, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Allergy Warning
A percentage of the population suffer from a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to dermatitis. We suggest wear protective gloves.
Handling guide
Handle magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and respect their power.
Power loss in heat
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
