Pros and cons of rare earth magnets.
Benefits
- Their strength is durable, and after approximately ten years it drops only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- Thanks to the shimmering finish, the coating of nickel, gold-plated, or silver gives an clean appearance,
- They are known for high magnetic induction at the operating surface, making them more effective,
- 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 potential of accurate shaping and customization to custom solutions, magnetic components can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Versatile presence in future technologies – they are utilized in data components, electromotive mechanisms, precision medical tools, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 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 prevent oxidation and corrosion.
- We suggest casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these products are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- with a thickness no less than 10 mm
- characterized by even structure
- with direct contact (without coatings)
- during detachment in a direction vertical to the mounting surface
- at temperature room level
What influences lifting capacity in practice
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Keep away from children
These products are not suitable for play. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.
Keep away from electronics
Be aware: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
Medical implants
Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Thermal limits
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Nickel allergy
Studies show that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or opt for versions in plastic housing.
Hand protection
Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Cards and drives
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Fire warning
Machining of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Do not underestimate power
Exercise caution. Rare earth magnets act from a long distance and snap with massive power, often faster than you can move away.
