Advantages and disadvantages of rare earth magnets.
Benefits
- They do not lose magnetism, even over approximately 10 years – the drop in strength is only ~1% (theoretically),
- Neodymium magnets remain remarkably resistant to magnetic field loss caused by external field sources,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Possibility of detailed creating as well as adapting to concrete needs,
- Huge importance in high-tech industry – they are utilized in magnetic memories, electric drive systems, advanced medical instruments, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Weaknesses
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose force 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. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- whose thickness reaches at least 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Air gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
GPS Danger
Note: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
Choking Hazard
Strictly keep magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are very dangerous.
Heat warning
Keep cool. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Data carriers
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Caution required
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Bone fractures
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Magnets are brittle
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Warning for allergy sufferers
Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose versions in plastic housing.
Fire warning
Powder created during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Warning for heart patients
Individuals with a pacemaker have to maintain an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.
