Strengths as well as weaknesses of neodymium magnets.
Strengths
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- Magnets very well defend themselves against demagnetization caused by ambient magnetic noise,
- A magnet with a metallic silver surface looks better,
- Magnetic induction on the surface of the magnet is maximum,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact machining as well as modifying to specific needs,
- Universal use in innovative solutions – they serve a role in mass storage devices, brushless drives, diagnostic systems, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated forms in magnets, we propose using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- with zero gap (without impurities)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet causes magnetic saturation, causing part of the power to be escaped into the air.
- Steel grade – 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 stronger the hold. Unevenness creates an air distance.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
H&S for magnets
Finger safety
Pinching hazard: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Cards and drives
Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Eye protection
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them breaking into small pieces.
Danger to pacemakers
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
GPS and phone interference
A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to prevent breaking the sensors.
Power loss in heat
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
Immense force
Exercise caution. Neodymium magnets act from a distance and connect with massive power, often faster than you can react.
Choking Hazard
Adult use only. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of children and animals.
Avoid contact if allergic
It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or choose coated magnets.
Do not drill into magnets
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
