Strengths as well as weaknesses of rare earth magnets.
Strengths
- Their strength is maintained, and after around 10 years it drops only by ~1% (theoretically),
- They maintain their magnetic properties even under close interference source,
- Thanks to the smooth finish, the layer of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of exact shaping as well as adapting to specific conditions,
- Universal use in innovative solutions – they are used in mass storage devices, brushless drives, precision medical tools, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these devices can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by smoothness
- without the slightest clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel type – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Shattering risk
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Sensitization to coating
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, refrain from direct skin contact and choose coated magnets.
Adults only
Adult use only. Small elements pose a choking risk, causing serious injuries. Store out of reach of kids and pets.
Powerful field
Be careful. Rare earth magnets attract from a distance and connect with massive power, often faster than you can move away.
Danger to pacemakers
Individuals with a pacemaker have to maintain an large gap from magnets. The magnetism can stop the operation of the life-saving device.
Keep away from computers
Do not bring magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Heat warning
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Do not drill into magnets
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Threat to navigation
Be aware: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Crushing force
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
