Strengths and weaknesses of rare earth magnets.
Strengths
- They retain attractive force for almost 10 years – the loss is just ~1% (based on simulations),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a metallic nickel surface has better aesthetics,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the ability to customize to individual projects,
- Wide application in advanced technology sectors – they are commonly used in HDD drives, electromotive mechanisms, medical equipment, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
What influences lifting capacity in practice
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (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).
- Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Crushing risk
Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Risk of cracking
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Precision electronics
Note: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.
Powerful field
Handle magnets with awareness. Their huge power can shock even professionals. Plan your moves and do not underestimate their power.
Magnetic media
Do not bring magnets near a purse, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Danger to the youngest
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from kids and pets.
Do not overheat magnets
Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Avoid contact if allergic
Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands and choose coated magnets.
Dust explosion hazard
Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
ICD Warning
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
