Pros and cons of rare earth magnets.
Benefits
- They do not lose power, even over approximately ten years – the drop in power is only ~1% (based on measurements),
- They possess excellent resistance to magnetism drop when exposed to external fields,
- Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnets exhibit maximum magnetic induction on the outer layer,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise forming as well as adjusting to complex needs,
- Huge importance in high-tech industry – they are used in computer drives, brushless drives, medical devices, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in miniature devices
Cons
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using a housing - magnetic mount.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Additionally, small elements of these products can be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a plate made of low-carbon steel, acting as a magnetic yoke
- with a thickness no less than 10 mm
- with a surface free of scratches
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet does not close the flux, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Safe handling of NdFeB magnets
Threat to electronics
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Do not underestimate power
Use magnets consciously. Their immense force can shock even professionals. Stay alert and respect their force.
Operating temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its properties and strength.
Mechanical processing
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Fragile material
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Precision electronics
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Swallowing risk
Absolutely keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.
Life threat
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Serious injuries
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
