Advantages as well as disadvantages of rare earth magnets.
Pros
- They do not lose power, even during nearly 10 years – the reduction in power is only ~1% (based on measurements),
- Neodymium magnets remain extremely resistant to magnetic field loss caused by external interference,
- A magnet with a shiny silver surface has an effective appearance,
- Magnetic induction on the working layer of the magnet is strong,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the option of precise shaping and customization to individualized requirements, magnetic components can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
- Wide application in high-tech industry – they are utilized in hard drives, electromotive mechanisms, advanced medical instruments, also modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- under conditions of no distance (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at conditions approx. 20°C
What influences lifting capacity in practice
- Gap (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Cast iron may attract less.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, 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 reduces the load capacity.
Safety rules for work with NdFeB magnets
Physical harm
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
This is not a toy
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store out of reach of kids and pets.
ICD Warning
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Cards and drives
Avoid bringing magnets near a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them shattering into small pieces.
Power loss in heat
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Threat to navigation
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Powerful field
Handle magnets consciously. Their huge power can shock even professionals. Stay alert and do not underestimate their force.
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.
Fire risk
Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
