Pros as well as cons of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets are distinguished by exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the surface of the magnet remains maximum,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in designing and the ability to adapt to specific needs,
- Wide application in modern industrial fields – they serve a role in computer drives, drive modules, precision medical tools, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- without any insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
- Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Do not underestimate power
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Beware of splinters
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Machining danger
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Medical implants
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Bodily injuries
Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Danger to the youngest
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Store away from children and animals.
Threat to navigation
GPS units and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Electronic hazard
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Demagnetization risk
Keep cool. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Metal Allergy
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and choose versions in plastic housing.
