Advantages and disadvantages of rare earth magnets.
Strengths
- They do not lose strength, even during nearly 10 years – the reduction in strength is only ~1% (theoretically),
- They are resistant to demagnetization induced by external disturbances,
- By covering with a reflective coating of nickel, the element presents an nice look,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- In view of the ability of flexible forming and adaptation to specialized solutions, NdFeB magnets can be modeled in a wide range of shapes and sizes, which expands the range of possible applications,
- Wide application in innovative solutions – they are used in hard drives, brushless drives, diagnostic systems, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing threads in the magnet and complex shapes - preferred is cover - magnet mounting.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a cross-section minimum 10 mm
- with an ground touching surface
- with total lack of distance (without coatings)
- under perpendicular force vector (90-degree angle)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not close the flux, causing part of the flux to be escaped into the air.
- Steel grade – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Safe handling of NdFeB magnets
Protect data
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Product not for children
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of children and animals.
Respect the power
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Machining danger
Powder created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Bone fractures
Big blocks can crush fingers in a fraction of a second. Do not put your hand between two attracting surfaces.
Precision electronics
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Eye protection
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Medical interference
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Nickel allergy
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and select coated magnets.
