Strengths as well as weaknesses of rare earth magnets.
Benefits
- They do not lose power, even over approximately 10 years – the drop in strength is only ~1% (according to tests),
- Neodymium magnets are highly resistant to loss of magnetic properties caused by external field sources,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- They feature high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the ability of accurate shaping and adaptation to custom solutions, magnetic components can be produced in a broad palette of shapes and sizes, which expands the range of possible applications,
- Versatile presence in modern industrial fields – they are used in computer drives, electromotive mechanisms, diagnostic systems, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions
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 raises their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, small components of these devices are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- with an ideally smooth contact surface
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular force vector (90-degree angle)
- at conditions approx. 20°C
Key elements affecting lifting force
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the holding force.
Safe handling of NdFeB magnets
Handling rules
Be careful. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.
Medical implants
Individuals with a heart stimulator must maintain an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
Fragile material
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Hand protection
Large magnets can crush fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Thermal limits
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Swallowing risk
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.
Fire warning
Dust generated during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
GPS and phone interference
Remember: neodymium magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
Sensitization to coating
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness happens, cease working with magnets and use protective gear.
Data carriers
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
