Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain full power for around 10 years – the drop is just ~1% (based on simulations),
- They retain their magnetic properties even under strong external field,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- In view of the ability of precise forming and customization to individualized solutions, magnetic components can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Universal use in future technologies – they are used in data components, electric drive systems, medical equipment, as well as technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- 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 resistant to moisture
- Due to limitations in producing nuts and complex forms in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- with a thickness no less than 10 mm
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer 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 holding force drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy steels lower magnetic permeability and lifting capacity.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Precautions when working with neodymium magnets
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into small pieces.
Pacemakers
Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Phone sensors
Remember: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.
Electronic hazard
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Conscious usage
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Heat warning
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Bone fractures
Big blocks can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Product not for children
Strictly keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are life-threatening.
Mechanical processing
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
