Strengths and weaknesses of rare earth magnets.
Benefits
- Their power is durable, and after around 10 years it decreases only by ~1% (theoretically),
- They maintain their magnetic properties even under close interference source,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to look better,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- 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...
- Possibility of exact creating as well as optimizing to concrete conditions,
- Huge importance in modern technologies – they are used in data components, electric motors, advanced medical instruments, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in small systems
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in special holders. 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 as well as 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
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these products are able to complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- with an ground contact surface
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
No play value
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Keep away from children and animals.
Keep away from computers
Data protection: Strong magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Combustion hazard
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Hand protection
Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Do not underestimate power
Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can move away.
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Precision electronics
A powerful magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Thermal limits
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and wear gloves.
Implant safety
Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
