Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the reflective layer of nickel, the element gains a professional look,
- They feature high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of detailed creating as well as adapting to precise applications,
- Significant place in modern technologies – they serve a role in magnetic memories, electric drive systems, medical devices, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions
Cons
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets lose force 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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in realizing threads and complicated forms in magnets, we recommend using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safe handling of NdFeB magnets
Impact on smartphones
Note: neodymium magnets produce a field that disrupts precision electronics. Keep a separation from your phone, device, and GPS.
Dust is flammable
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Warning for allergy sufferers
Studies show that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid direct skin contact and select versions in plastic housing.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Immense force
Exercise caution. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can react.
Product not for children
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are fatal.
Risk of cracking
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Finger safety
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Protect data
Data protection: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Implant safety
Warning for patients: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.
