Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They retain attractive force for around ten years – the drop is just ~1% (according to analyses),
- Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
- A magnet with a smooth silver surface looks better,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of detailed shaping and adapting to complex conditions,
- Key role in future technologies – they find application in computer drives, electric drive systems, precision medical tools, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating nuts in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension is min. 10 mm
- with an ground contact surface
- under conditions of no distance (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Immense force
Handle with care. Neodymium magnets act from a distance and connect with massive power, often quicker than you can react.
Physical harm
Large magnets can smash fingers instantly. Do not place your hand between two strong magnets.
Keep away from children
NdFeB magnets are not intended for children. Eating several magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Implant safety
For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Precision electronics
GPS units and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.
Warning for allergy sufferers
Studies show that nickel (the usual finish) is a common allergen. If you have an allergy, prevent touching magnets with bare hands or choose encased magnets.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Heat warning
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Threat to electronics
Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
