Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- 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 modifying to individual requirements,
- Versatile presence in future technologies – they are utilized in HDD drives, brushless drives, medical equipment, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complicated forms - recommended is casing - magnetic holder.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a sheet made of high-permeability steel, functioning as a circuit closing element
- with a thickness of at least 10 mm
- with a plane perfectly flat
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction vertical to the plane
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not accept the full field, causing part of the power to be escaped into the air.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
- Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safe handling of NdFeB magnets
Power loss in heat
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Impact on smartphones
A powerful magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Cards and drives
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Mechanical processing
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Physical harm
Big blocks can break fingers instantly. Under no circumstances put your hand between two strong magnets.
Caution required
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Warning for heart patients
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Product not for children
Only for adults. Small elements pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
