Advantages as well as disadvantages of rare earth magnets.
Benefits
- They do not lose magnetism, even during nearly 10 years – the reduction in power is only ~1% (theoretically),
- Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by external field sources,
- By covering with a shiny coating of gold, the element presents an professional look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Considering the option of flexible shaping and adaptation to custom solutions, magnetic components can be modeled in a wide range of geometric configurations, which expands the range of possible applications,
- Key role in modern technologies – they are utilized in computer drives, electric motors, diagnostic systems, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- with an ground contact surface
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Operating temperature
Avoid heat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Do not underestimate power
Exercise caution. Rare earth magnets act from a long distance and snap with huge force, often faster than you can move away.
Fragile material
Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Magnetic interference
An intense magnetic field negatively affects the operation of compasses in phones and navigation systems. Maintain magnets near a device to prevent damaging the sensors.
Danger to the youngest
Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Dust is flammable
Powder generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Danger to pacemakers
Individuals with a pacemaker must keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Keep away from computers
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Warning for allergy sufferers
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop working with magnets and use protective gear.
Finger safety
Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
