Advantages and disadvantages of rare earth magnets.
Strengths
- They do not lose magnetism, even during approximately ten years – the reduction in strength is only ~1% (according to tests),
- Magnets effectively protect themselves against demagnetization caused by foreign field sources,
- By applying a shiny layer of gold, the element acquires an elegant look,
- Magnetic induction on the surface of the magnet turns out to be very high,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the option of flexible shaping and customization to unique requirements, neodymium magnets can be created in a wide range of forms and dimensions, which increases their versatility,
- Key role in electronics industry – they are commonly used in computer drives, motor assemblies, precision medical tools, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of making nuts in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- with an ground touching surface
- under conditions of no distance (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (paint, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
- Plate material – mild steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Smoothness – ideal contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the holding force.
Warnings
Powerful field
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Combustion hazard
Powder created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Electronic hazard
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Warning for heart patients
Patients with a ICD must keep an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.
GPS Danger
Remember: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Nickel coating and allergies
A percentage of the population have a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Frequent touching can result in dermatitis. We recommend wear protective gloves.
Heat sensitivity
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Crushing risk
Big blocks can crush fingers instantly. Never put your hand betwixt two attracting surfaces.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.
Adults only
Only for adults. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of children and animals.
