Pros and cons of rare earth magnets.
Advantages
- Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They do not lose their magnetic properties even under strong external field,
- In other words, due to the reflective finish of nickel, the element gains visual value,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
- Neodymium magnets are characterized by extremely 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 accurate creating and optimizing to complex needs,
- Universal use in innovative solutions – they serve a role in HDD drives, electric drive systems, diagnostic systems, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions
Limitations
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complex shapes in magnets, we recommend using casing - magnetic mount.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic field
- whose transverse dimension equals approx. 10 mm
- with an polished touching surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Physical harm
Large magnets can break fingers instantly. Never place your hand between two attracting surfaces.
Conscious usage
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Product not for children
Absolutely keep magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Compass and GPS
A strong magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.
Fragile material
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them cracking into shards.
Dust is flammable
Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and use protective gear.
Implant safety
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Operating temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Protect data
Avoid bringing magnets near a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
