Strengths and weaknesses of rare earth magnets.
Benefits
- They retain magnetic properties for around 10 years – the loss is just ~1% (in theory),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- Thanks to the shiny finish, the plating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the working layer of the magnet remains strong,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of detailed modeling and adjusting to defined applications,
- Huge importance in future technologies – they serve a role in computer drives, electromotive mechanisms, diagnostic systems, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complicated forms - preferred is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- with zero gap (no impurities)
- under vertical force vector (90-degree angle)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Warnings
Pinching danger
Risk of injury: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Maximum temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Handling rules
Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can move away.
Choking Hazard
Always keep magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are very dangerous.
Fragile material
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them cracking into small pieces.
Data carriers
Data protection: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, timepieces).
Precision electronics
Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Medical implants
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Combustion hazard
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Allergy Warning
A percentage of the population have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Extended handling can result in dermatitis. We strongly advise use safety gloves.
