Pros and cons of Nd2Fe14B magnets.
Benefits
- They retain magnetic properties for around 10 years – the drop is just ~1% (according to analyses),
- They possess excellent resistance to magnetism drop as a result of opposing magnetic fields,
- In other words, due to the glossy finish of nickel, the element becomes visually attractive,
- They are known for 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 shape) even at a temperature of 230°C or more...
- Possibility of accurate machining as well as optimizing to precise needs,
- Wide application in modern industrial fields – they are used in hard drives, drive modules, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these devices can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a sheet made of mild steel, serving as a circuit closing element
- whose transverse dimension is min. 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Eye protection
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them shattering into shards.
Magnetic interference
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Allergic reactions
Certain individuals experience a sensitization to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. We recommend use protective gloves.
This is not a toy
Absolutely keep magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.
Do not underestimate power
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Magnetic media
Intense magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Thermal limits
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Crushing force
Large magnets can break fingers in a fraction of a second. Do not place your hand between two strong magnets.
Danger to pacemakers
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Dust is flammable
Dust generated during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
