Strengths as well as weaknesses of neodymium magnets.
Pros
- They do not lose magnetism, even after around ten years – the reduction in strength is only ~1% (theoretically),
- They feature excellent resistance to magnetic field loss when exposed to external magnetic sources,
- A magnet with a metallic nickel surface looks better,
- Magnets have very high magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to flexibility in forming and the capacity to customize to unusual requirements,
- Huge importance in electronics industry – they are commonly used in HDD drives, electromotive mechanisms, diagnostic systems, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a sheet made of mild steel, serving as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- without any air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Key elements affecting lifting force
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Phone sensors
Be aware: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
Beware of splinters
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Safe distance
Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Nickel allergy
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands and select versions in plastic housing.
Danger to pacemakers
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Operating temperature
Do not overheat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).
Bodily injuries
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Dust is flammable
Dust created during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Do not give to children
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are very dangerous.
Caution required
Handle magnets consciously. Their huge power can surprise even experienced users. Plan your moves and respect their force.
