Pros and cons of Nd2Fe14B magnets.
Benefits
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under close interference source,
- A magnet with a smooth nickel surface looks better,
- Magnets exhibit huge magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the possibility of free molding and adaptation to custom needs, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in advanced technology sectors – they find application in hard drives, electric drive systems, diagnostic systems, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of high-permeability steel, functioning as a circuit closing element
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- with zero gap (no paint)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Lifting capacity in practice – influencing factors
- Gap (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Health Danger
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Heat warning
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Magnetic media
Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).
Adults only
Strictly store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are fatal.
Fire warning
Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Physical harm
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Immense force
Use magnets consciously. Their powerful strength can shock even experienced users. Stay alert and respect their power.
Threat to navigation
Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Sensitization to coating
A percentage of the population suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact can result in a rash. We recommend wear safety gloves.
Eye protection
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into small pieces.
