Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They are resistant to demagnetization induced by external magnetic fields,
- A magnet with a shiny silver surface looks better,
- Magnets possess extremely high magnetic induction on the active area,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the ability to customize to specific needs,
- Versatile presence in electronics industry – they find application in magnetic memories, electric motors, medical devices, and technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of creating threads in the magnet and complex forms - preferred is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products are able to 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
Maximum magnetic pulling force – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic flux
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (paint, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times lower (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.
- Material composition – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Phone sensors
Note: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
Do not drill into magnets
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Do not overheat magnets
Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Electronic hazard
Avoid bringing magnets near a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Adults only
Neodymium magnets are not suitable for play. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.
Handling rules
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Danger to pacemakers
People with a ICD should keep an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Avoid contact if allergic
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
Physical harm
Large magnets can break fingers instantly. Do not put your hand between two strong magnets.
Fragile material
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
