Pros as well as cons of rare earth magnets.
Benefits
- They retain attractive force for around 10 years – the loss is just ~1% (based on simulations),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external interference,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise machining as well as adapting to specific needs,
- Huge importance in innovative solutions – they are utilized in computer drives, motor assemblies, precision medical tools, also technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated shapes in magnets, we propose using casing - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process 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 affects it?
- using a plate made of low-carbon steel, serving as a magnetic yoke
- whose thickness equals approx. 10 mm
- with a plane free of scratches
- without any air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Eye protection
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Nickel allergy
Some people suffer from a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to skin redness. We suggest wear safety gloves.
Keep away from electronics
A powerful magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Flammability
Combustion risk: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Crushing risk
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Handling rules
Handle with care. Rare earth magnets act from a distance and connect with huge force, often faster than you can react.
Demagnetization risk
Keep cool. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Data carriers
Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
No play value
These products are not suitable for play. Eating multiple magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Danger to pacemakers
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
