Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They retain full power for nearly ten years – the drop is just ~1% (based on simulations),
- They possess excellent resistance to magnetism drop when exposed to external magnetic sources,
- A magnet with a smooth gold surface is more attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the option of accurate forming and adaptation to custom needs, neodymium magnets can be manufactured in a variety of shapes and sizes, which amplifies use scope,
- Significant place in innovative solutions – they find application in HDD drives, drive modules, medical devices, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, small components 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
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of low-carbon steel, acting as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- with an ground touching surface
- under conditions of no distance (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Distance – existence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Warnings
Magnetic interference
An intense magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.
Handling rules
Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and respect their power.
Safe distance
Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Shattering risk
Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
No play value
Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are very dangerous.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Never put your hand between two strong magnets.
Dust is flammable
Dust generated during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Allergic reactions
A percentage of the population suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause a rash. We recommend use safety gloves.
Maximum temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Life threat
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
