Advantages as well as disadvantages of rare earth magnets.
Pros
- Their power remains stable, and after approximately 10 years it drops only by ~1% (according to research),
- They feature excellent resistance to magnetism drop when exposed to external fields,
- A magnet with a metallic gold surface has better aesthetics,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of precise shaping as well as adjusting to defined conditions,
- Fundamental importance in future technologies – they find application in mass storage devices, brushless drives, precision medical tools, and complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- 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.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of producing nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without any air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Distance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost to the other side.
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Life threat
Individuals with a heart stimulator must keep an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.
Shattering risk
Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets leads to them breaking into small pieces.
Keep away from electronics
GPS units and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Electronic hazard
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Hand protection
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Thermal limits
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Do not give to children
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
Dust explosion hazard
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Do not underestimate power
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Allergic reactions
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
