Pros and cons of rare earth magnets.
Pros
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- Magnets effectively protect themselves against loss of magnetization caused by external fields,
- A magnet with a shiny gold surface looks better,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in constructing and the ability to customize to client solutions,
- Universal use in advanced technology sectors – they serve a role in computer drives, drive modules, diagnostic systems, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems
Weaknesses
- At very 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 their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability 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 resistant to moisture, when using outdoors
- Limited possibility of creating threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Highest magnetic holding force – what contributes to it?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- with a cross-section no less than 10 mm
- with an polished touching surface
- without any clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin plate does not close the flux, causing part of the flux to be wasted into the air.
- Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Impact on smartphones
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Metal Allergy
Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact or opt for encased magnets.
Electronic hazard
Avoid bringing magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Serious injuries
Risk of injury: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Health Danger
Patients with a ICD have to keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Do not underestimate power
Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their power.
Heat sensitivity
Do not overheat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
This is not a toy
NdFeB magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates immediate surgery.
Fragile material
NdFeB magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them breaking into shards.
