Strengths as well as weaknesses of rare earth magnets.
Pros
- They do not lose magnetism, even after around ten years – the drop in lifting capacity is only ~1% (theoretically),
- They possess excellent resistance to magnetism drop as a result of external fields,
- Thanks to the elegant finish, the coating of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- Magnets exhibit extremely high magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the possibility of flexible shaping and adaptation to individualized projects, NdFeB magnets can be created in a wide range of geometric configurations, which amplifies use scope,
- Universal use in future technologies – they are used in hard drives, drive modules, precision medical tools, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their power 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating nuts in the magnet and complicated forms - recommended is cover - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- with an polished contact surface
- under conditions of no distance (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at room temperature
Key elements affecting lifting force
- Distance (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin steel causes magnetic saturation, causing part of the power to be lost into the air.
- Steel type – mild steel attracts best. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Data carriers
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Avoid contact if allergic
A percentage of the population suffer from a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact can result in a rash. We strongly advise wear safety gloves.
This is not a toy
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are life-threatening.
Finger safety
Big blocks can smash fingers instantly. Never place your hand between two strong magnets.
Dust explosion hazard
Powder generated during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Thermal limits
Avoid heat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Conscious usage
Exercise caution. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can move away.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets leads to them cracking into shards.
Medical implants
People with a heart stimulator have to keep an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
GPS and phone interference
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
