Advantages as well as disadvantages of neodymium magnets.
Advantages
- They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization induced by external field influence,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Due to the ability of precise shaping and adaptation to specialized requirements, magnetic components can be created in a variety of shapes and sizes, which makes them more universal,
- Huge importance in innovative solutions – they find application in hard drives, electric drive systems, precision medical tools, also complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complicated forms in magnets, we propose using a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- with a thickness no less than 10 mm
- characterized by smoothness
- without the slightest insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Air gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Material brittleness
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Keep away from electronics
GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Protect data
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Finger safety
Risk of injury: The attraction force is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Implant safety
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Product not for children
Only for adults. Small elements pose a choking risk, causing serious injuries. Store out of reach of kids and pets.
Metal Allergy
A percentage of the population experience a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Extended handling can result in an allergic reaction. It is best to wear protective gloves.
Permanent damage
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Dust explosion hazard
Powder produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Respect the power
Use magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their power.
