Strengths and weaknesses of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetism drop due to opposing magnetic fields,
- By using a shiny coating of nickel, the element presents an aesthetic look,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise machining as well as optimizing to individual needs,
- Wide application in modern technologies – they find application in magnetic memories, electromotive mechanisms, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in small systems
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated shapes in magnets, we propose using a housing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- using a sheet made of high-permeability steel, functioning as a magnetic yoke
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- under axial force vector (90-degree angle)
- at temperature room level
Key elements affecting lifting force
- Clearance – existence of foreign body (paint, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Combustion hazard
Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Pinching danger
Big blocks can crush fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Pacemakers
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Product not for children
NdFeB magnets are not toys. Eating a few magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact and opt for encased magnets.
Precision electronics
GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Handling rules
Handle magnets consciously. Their immense force can shock even professionals. Plan your moves and respect their power.
Operating temperature
Control the heat. Heating the magnet to high heat will ruin its properties and strength.
Data carriers
Very strong magnetic fields can destroy records on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Magnets are brittle
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
