Advantages and disadvantages of rare earth magnets.
Benefits
- They retain magnetic properties for almost ten years – the loss is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets achieve maximum magnetic induction on a small area, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of exact forming as well as optimizing to specific conditions,
- Fundamental importance in electronics industry – they serve a role in magnetic memories, electromotive mechanisms, advanced medical instruments, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in small systems
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise 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, when using outdoors
- We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these products can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a base made of structural steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- under conditions of no distance (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Distance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Steel type – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Flammability
Combustion risk: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Finger safety
Protect your hands. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
GPS Danger
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and navigation systems.
Safe distance
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).
Life threat
People with a heart stimulator have to keep an large gap from magnets. The magnetic field can interfere with the operation of the life-saving device.
Safe operation
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
Material brittleness
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Swallowing risk
Only for adults. Tiny parts can be swallowed, leading to severe trauma. Keep out of reach of kids and pets.
