Advantages and disadvantages of rare earth magnets.
Pros
- Their magnetic field remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They feature excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- In other words, due to the glossy finish of gold, the element looks attractive,
- Neodymium magnets generate maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of accurate forming and adjusting to complex needs,
- Versatile presence in modern industrial fields – they are used in computer drives, electric drive systems, diagnostic systems, and modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power 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 durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated forms in magnets, we propose using cover - magnetic mount.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Highest magnetic holding force – what affects it?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- whose transverse dimension is min. 10 mm
- with an ideally smooth touching surface
- with zero gap (no impurities)
- during detachment in a direction vertical to the mounting surface
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
- Surface structure – the more even the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Keep away from electronics
Note: neodymium magnets generate a field that interferes with sensitive sensors. Keep a separation from your phone, tablet, and navigation systems.
Medical implants
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Fragile material
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
Threat to electronics
Equipment safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Do not overheat magnets
Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Respect the power
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
No play value
Only for adults. Small elements can be swallowed, leading to severe trauma. Store out of reach of kids and pets.
Physical harm
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Flammability
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Warning for allergy sufferers
It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose encased magnets.
