Advantages and disadvantages of rare earth magnets.
Advantages
- They do not lose power, even during approximately 10 years – the drop in power is only ~1% (based on measurements),
- They are resistant to demagnetization induced by external field influence,
- By using a smooth coating of nickel, the element presents an aesthetic look,
- Magnets are distinguished by huge magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of precise creating and adapting to defined needs,
- Huge importance in modern technologies – they serve a role in data components, brushless drives, diagnostic systems, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complex shapes - preferred is casing - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness of at least 10 mm
- with a surface cleaned and smooth
- with direct contact (no coatings)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Precision electronics
Remember: rare earth magnets generate a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and GPS.
Thermal limits
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Sensitization to coating
It is widely known that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose coated magnets.
Implant safety
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Do not drill into magnets
Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Eye protection
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them cracking into shards.
Respect the power
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Keep away from computers
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Danger to the youngest
Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
Crushing force
Large magnets can smash fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
