Pros and cons of rare earth magnets.
Advantages
- They do not lose power, even over around ten years – the reduction in power is only ~1% (according to tests),
- They are resistant to demagnetization induced by external disturbances,
- A magnet with a shiny silver surface looks better,
- Magnets possess exceptionally strong magnetic induction on the active area,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
- Due to the potential of precise molding and customization to custom requirements, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which increases their versatility,
- Wide application in future technologies – they find application in magnetic memories, brushless drives, diagnostic systems, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with a surface perfectly flat
- with zero gap (without coatings)
- under axial force direction (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Health Danger
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Impact on smartphones
GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Conscious usage
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Bone fractures
Large magnets can crush fingers instantly. Do not place your hand between two strong magnets.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them cracking into small pieces.
Nickel allergy
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact and select coated magnets.
Choking Hazard
Always keep magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.
Cards and drives
Do not bring magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Operating temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Dust explosion hazard
Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
