Pros and cons of rare earth magnets.
Pros
- They do not lose power, even during around ten years – the drop in strength is only ~1% (based on measurements),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external interference,
- In other words, due to the glossy finish of silver, the element gains visual value,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of detailed forming and adapting to precise applications,
- Universal use in innovative solutions – they are commonly used in HDD drives, electric motors, medical devices, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Cons
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize 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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited possibility of producing nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- with direct contact (no paint)
- during pulling in a direction perpendicular to the mounting surface
- at temperature room level
Practical lifting capacity: influencing factors
- Gap 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.
- Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel causes magnetic saturation, causing part of the power to be escaped into the air.
- Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.
Hand protection
Large magnets can smash fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.
Combustion hazard
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Precision electronics
Navigation devices and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Allergic reactions
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
No play value
Always store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.
Shattering risk
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Maximum temperature
Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Protect data
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Do not underestimate power
Handle magnets with awareness. Their immense force can surprise even professionals. Plan your moves and respect their power.
Medical interference
For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
