Pros as well as cons of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- They show high resistance to demagnetization induced by external disturbances,
- Thanks to the reflective finish, the layer of nickel, gold, or silver gives an aesthetic appearance,
- Neodymium magnets ensure maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to versatility in designing and the ability to modify to complex applications,
- Huge importance in modern industrial fields – they are utilized in hard drives, brushless drives, advanced medical instruments, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- 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 protects them against impacts but also increases their 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these products can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by lack of roughness
- with zero gap (no paint)
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted to the other side.
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Precautions when working with neodymium magnets
Life threat
Patients with a heart stimulator should maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.
Adults only
Always keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are fatal.
Crushing force
Danger of trauma: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Handling rules
Exercise caution. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can react.
GPS Danger
A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Fire risk
Dust produced during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Eye protection
Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Allergy Warning
It is widely known that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact and choose versions in plastic housing.
Maximum temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Keep away from computers
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
