Strengths as well as weaknesses of rare earth magnets.
Advantages
- They retain attractive force for around ten years – the drop is just ~1% (in theory),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the smooth finish of nickel, the element gains visual value,
- Magnetic induction on the working layer of the magnet turns out to be impressive,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the option of free molding and adaptation to specialized solutions, magnetic components can be modeled in a broad palette of forms and dimensions, which makes them more universal,
- Huge importance in future technologies – they find application in magnetic memories, electromotive mechanisms, diagnostic systems, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in compact constructions
Limitations
- 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.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of producing threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with a plane cleaned and smooth
- under conditions of no distance (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped into the air.
- Plate material – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
Medical interference
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Keep away from children
Always keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are tragic.
Protect data
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Warning for allergy sufferers
Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and choose coated magnets.
Dust is flammable
Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Safe operation
Handle with care. Neodymium magnets act from a long distance and connect with huge force, often faster than you can move away.
Maximum temperature
Control the heat. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Finger safety
Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Compass and GPS
An intense magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Material brittleness
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets will cause them breaking into shards.
