Advantages and disadvantages of rare earth magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- They possess excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- By covering with a shiny layer of silver, the element presents an aesthetic look,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Due to the potential of precise forming and adaptation to custom solutions, magnetic components can be manufactured in a variety of shapes and sizes, which makes them more universal,
- Wide application in modern technologies – they are commonly used in hard drives, brushless drives, medical devices, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- under axial force vector (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Data carriers
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Demagnetization risk
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.
Beware of splinters
Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Handling guide
Handle with care. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can react.
Crushing force
Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Allergic reactions
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent touching magnets with bare hands and opt for versions in plastic housing.
Swallowing risk
These products are not toys. Swallowing a few magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
Do not drill into magnets
Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
GPS and phone interference
A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to prevent breaking the sensors.
Implant safety
People with a ICD have to keep an large gap from magnets. The magnetic field can disrupt the operation of the implant.
