Advantages and disadvantages of neodymium magnets.
Benefits
- They have constant strength, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under strong external field,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet turns out to be very high,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise machining as well as adjusting to atypical needs,
- Significant place in modern technologies – they are used in magnetic memories, electromotive mechanisms, medical devices, and other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- with a cross-section minimum 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Safe operation
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Demagnetization risk
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Serious injuries
Risk of injury: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Impact on smartphones
Be aware: rare earth magnets generate a field that interferes with sensitive sensors. Keep a separation from your phone, tablet, and navigation systems.
Threat to electronics
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact and choose coated magnets.
Implant safety
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Eye protection
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them cracking into shards.
Fire warning
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Adults only
These products are not intended for children. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.
