Pros as well as cons of neodymium magnets.
Benefits
- They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They show high resistance to demagnetization induced by external disturbances,
- Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
- They show high magnetic induction at the operating surface, which increases their power,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- In view of the potential of flexible shaping and adaptation to custom requirements, magnetic components can be created in a wide range of forms and dimensions, which amplifies use scope,
- Versatile presence in modern industrial fields – they serve a role in magnetic memories, electric motors, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of producing nuts in the magnet and complicated forms - recommended is casing - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices can be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Highest magnetic holding force – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- with direct contact (without paint)
- during detachment in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Clearance – existence of any layer (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Base massiveness – too thin plate causes magnetic saturation, causing part of the power to be wasted into the air.
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.
H&S for magnets
Dust explosion hazard
Powder created during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Safe operation
Handle magnets consciously. Their immense force can shock even professionals. Plan your moves and do not underestimate their power.
Protect data
Intense magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
GPS Danger
GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Maximum temperature
Do not overheat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Danger to the youngest
Neodymium magnets are not intended for children. Eating multiple magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.
Warning for heart patients
People with a heart stimulator must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Crushing risk
Risk of injury: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Skin irritation risks
Certain individuals experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause skin redness. We recommend use protective gloves.
Shattering risk
NdFeB magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them cracking into shards.
