Pros and cons of rare earth magnets.
Advantages
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets perfectly resist against loss of magnetization caused by external fields,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets generate maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the possibility of free forming and customization to unique projects, magnetic components can be created in a variety of geometric configurations, which makes them more universal,
- Significant place in innovative solutions – they find application in computer drives, electromotive mechanisms, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complex forms in magnets, we propose using a housing - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what contributes to it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Warnings
Choking Hazard
Strictly keep magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.
Hand protection
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Pacemakers
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Combustion hazard
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Heat sensitivity
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Respect the power
Be careful. Neodymium magnets act from a distance and snap with massive power, often quicker than you can move away.
GPS and phone interference
An intense magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to avoid damaging the sensors.
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and wear gloves.
Keep away from computers
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
