Advantages as well as disadvantages of rare earth magnets.
Strengths
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under close interference source,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the surface of the magnet is very high,
- 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 accurate forming as well as modifying to concrete applications,
- Universal use in innovative solutions – they serve a role in HDD drives, drive modules, medical devices, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated forms in magnets, we propose using a housing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a sheet made of low-carbon steel, functioning as a magnetic yoke
- whose thickness is min. 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- in temp. approx. 20°C
Key elements affecting lifting force
- Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be escaped into the air.
- Chemical composition of the base – mild steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Power loss in heat
Keep cool. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Safe distance
Device Safety: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Dust explosion hazard
Dust created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Risk of cracking
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Threat to navigation
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.
Adults only
Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are very dangerous.
Pinching danger
Large magnets can crush fingers instantly. Never put your hand betwixt two attracting surfaces.
Conscious usage
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Danger to pacemakers
Patients with a pacemaker should keep an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Skin irritation risks
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or select encased magnets.
