Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- Their strength is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They possess excellent resistance to magnetism drop as a result of external fields,
- Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in constructing and the capacity to customize to client solutions,
- Universal use in future technologies – they are utilized in mass storage devices, electromotive mechanisms, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in compact constructions
Cons
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited possibility of creating nuts in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a base made of mild steel, perfectly concentrating the magnetic field
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- with direct contact (without coatings)
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance – existence of any layer (paint, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be lost to the other side.
- Chemical composition of the base – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Swallowing risk
Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Dust explosion hazard
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Conscious usage
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Operating temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Serious injuries
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Danger to pacemakers
Individuals with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can disrupt the operation of the life-saving device.
Material brittleness
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Electronic devices
Device Safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Precision electronics
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Warning for allergy sufferers
Medical facts indicate that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or select coated magnets.
