Advantages as well as disadvantages of rare earth magnets.
Advantages
- They do not lose power, even over nearly ten years – the reduction in lifting capacity is only ~1% (theoretically),
- They retain their magnetic properties even under strong external field,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Possibility of detailed machining and adjusting to specific applications,
- Key role in future technologies – they are utilized in data components, electromotive mechanisms, diagnostic systems, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited possibility of creating nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- with a thickness no less than 10 mm
- characterized by smoothness
- with direct contact (without coatings)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be wasted to the other side.
- Metal type – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Fragile material
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Do not drill into magnets
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Choking Hazard
Strictly store magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.
Warning for heart patients
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Crushing risk
Large magnets can crush fingers instantly. Under no circumstances put your hand between two attracting surfaces.
GPS Danger
Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a safe distance from your mobile, device, and GPS.
Demagnetization risk
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
Safe distance
Data protection: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Immense force
Be careful. Rare earth magnets attract from a long distance and connect with huge force, often quicker than you can react.
