Pros and cons of rare earth magnets.
Advantages
- They do not lose power, even during nearly ten years – the decrease in strength is only ~1% (theoretically),
- Neodymium magnets remain exceptionally resistant to magnetic field loss caused by external interference,
- By using a lustrous coating of gold, the element acquires an aesthetic look,
- Magnetic induction on the surface of the magnet remains maximum,
- 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...
- Thanks to modularity in forming and the ability to adapt to individual projects,
- Versatile presence in innovative solutions – they are utilized in mass storage devices, drive modules, diagnostic systems, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- At very strong impacts they can crack, 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 decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited possibility of producing threads in the magnet and complex shapes - recommended is casing - mounting mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- with a cross-section minimum 10 mm
- with an ground touching surface
- with total lack of distance (without impurities)
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Warning for allergy sufferers
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or opt for coated magnets.
Medical implants
Patients with a heart stimulator should maintain an large gap from magnets. The magnetic field can stop the operation of the implant.
Magnetic media
Avoid bringing magnets near a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Danger to the youngest
Neodymium magnets are not intended for children. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which poses a direct threat to life and necessitates immediate surgery.
Do not underestimate power
Handle magnets with awareness. Their immense force can surprise even professionals. Plan your moves and respect their power.
Eye protection
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them breaking into small pieces.
Heat sensitivity
Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Bodily injuries
Large magnets can break fingers instantly. Never place your hand between two strong magnets.
Dust explosion hazard
Dust generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Magnetic interference
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
