Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their strength is maintained, and after around 10 years it decreases only by ~1% (according to research),
- They are noted for resistance to demagnetization induced by external disturbances,
- By covering with a shiny coating of silver, the element acquires an proper look,
- Magnetic induction on the working layer of the magnet remains very high,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- In view of the potential of flexible molding and customization to unique requirements, neodymium magnets can be modeled in a wide range of forms and dimensions, which amplifies use scope,
- Wide application in modern technologies – they are utilized in mass storage devices, motor assemblies, diagnostic systems, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making nuts in the magnet and complicated forms - recommended is a housing - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- using a base made of mild steel, serving as a magnetic yoke
- with a thickness no less than 10 mm
- with a surface perfectly flat
- with total lack of distance (no coatings)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Lifting capacity in real conditions – factors
- Distance (between the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Direction of force – 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).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Cards and drives
Very strong magnetic fields can destroy records on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Pacemakers
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Safe operation
Handle with care. Rare earth magnets act from a distance and connect with massive power, often quicker than you can move away.
Dust is flammable
Dust produced during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Crushing risk
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Do not give to children
Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.
Impact on smartphones
A strong magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Material brittleness
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Avoid contact if allergic
Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact or choose encased magnets.
Power loss in heat
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
