Strengths and weaknesses of rare earth magnets.
Advantages
- They have constant strength, and over around ten years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are remarkably resistant to demagnetization caused by magnetic disturbances,
- In other words, due to the aesthetic finish of gold, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of exact forming and adapting to precise conditions,
- Fundamental importance in advanced technology sectors – they find application in HDD drives, brushless drives, advanced medical instruments, also technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complex shapes - preferred is cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a sheet made of low-carbon steel, functioning as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at standard ambient temperature
Key elements affecting lifting force
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – high temperature weakens 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 attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Medical implants
Individuals with a heart stimulator should maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Fire warning
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Pinching danger
Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Operating temperature
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Handling rules
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Magnet fragility
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Nickel coating and allergies
Certain individuals suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Prolonged contact might lead to an allergic reaction. It is best to wear protective gloves.
Do not give to children
Strictly store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.
Magnetic media
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
GPS and phone interference
Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and GPS.
