Advantages as well as disadvantages of rare earth magnets.
Advantages
- They do not lose strength, even during approximately 10 years – the drop in strength is only ~1% (theoretically),
- They feature excellent resistance to magnetism drop as a result of external fields,
- A magnet with a smooth nickel surface has better aesthetics,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to versatility in constructing and the capacity to customize to client solutions,
- Huge importance in future technologies – they are utilized in HDD drives, drive modules, advanced medical instruments, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of making nuts in the magnet and complicated forms - preferred is a housing - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane cleaned and smooth
- without any air gap between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Heat sensitivity
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them cracking into small pieces.
Keep away from electronics
A powerful magnetic field disrupts the operation of compasses in phones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
Respect the power
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Fire warning
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Medical implants
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Choking Hazard
These products are not intended for children. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Allergic reactions
Some people suffer from a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling might lead to skin redness. We suggest wear safety gloves.
Electronic devices
Equipment safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Physical harm
Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
