Advantages as well as disadvantages of rare earth magnets.
Strengths
- Their strength remains stable, and after approximately ten years it drops only by ~1% (according to research),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by external interference,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to look better,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of individual shaping as well as adapting to specific conditions,
- Huge importance in innovative solutions – they serve a role in mass storage devices, drive modules, advanced medical instruments, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices
Limitations
- At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in producing nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these products can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by even structure
- with total lack of distance (no paint)
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Immense force
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Choking Hazard
Strictly store magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are life-threatening.
Serious injuries
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Cards and drives
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Life threat
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Threat to navigation
Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Combustion hazard
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Maximum temperature
Keep cool. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
