Advantages and disadvantages of rare earth magnets.
Benefits
- They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
- They have excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- In other words, due to the metallic layer of nickel, the element gains visual value,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the option of free shaping and customization to specialized requirements, magnetic components can be modeled in a variety of forms and dimensions, which increases their versatility,
- Universal use in modern industrial fields – they are commonly used in HDD drives, electric drive systems, diagnostic systems, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in miniature devices
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- on a block made of structural steel, effectively closing the magnetic field
- with a cross-section minimum 10 mm
- characterized by even structure
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin sheet does not close the flux, causing part of the power to be wasted to the other side.
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Sensitization to coating
Some people have a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Frequent touching may cause a rash. It is best to use safety gloves.
Respect the power
Exercise caution. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.
Health Danger
Patients with a pacemaker should keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Heat sensitivity
Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.
Magnetic media
Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Combustion hazard
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
GPS and phone interference
Be aware: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.
Material brittleness
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Choking Hazard
These products are not intended for children. Swallowing a few magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
Bodily injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
