Pros as well as cons of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets perfectly protect themselves against loss of magnetization caused by external fields,
- By applying a reflective layer of nickel, the element presents an aesthetic look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- 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...
- Thanks to modularity in designing and the ability to modify to complex applications,
- Significant place in innovative solutions – they are utilized in computer drives, electromotive mechanisms, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making threads in the magnet and complex shapes - preferred is cover - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be wasted into the air.
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Warnings
Keep away from children
Strictly store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are tragic.
Bone fractures
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Precision electronics
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Caution required
Use magnets with awareness. Their immense force can shock even professionals. Be vigilant and do not underestimate their force.
Fire risk
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
ICD Warning
Individuals with a heart stimulator have to maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Shattering risk
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Thermal limits
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Cards and drives
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
Sensitization to coating
It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands and opt for encased magnets.
