Pros as well as cons of rare earth magnets.
Strengths
- They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- Thanks to the shiny finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- Magnets exhibit maximum magnetic induction on the outer side,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of accurate creating and optimizing to concrete needs,
- Huge importance in advanced technology sectors – they are utilized in computer drives, electric motors, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects 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, when using outdoors
- Limited ability of producing nuts in the magnet and complicated shapes - preferred is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these products are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- characterized by even structure
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be escaped into the air.
- Metal type – different alloys attracts identically. High carbon content worsen the attraction effect.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Do not drill into magnets
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
ICD Warning
For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Do not overheat magnets
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Pinching danger
Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Cards and drives
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Respect the power
Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can move away.
Shattering risk
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
No play value
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Impact on smartphones
GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Warning for allergy sufferers
A percentage of the population suffer from a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact may cause skin redness. We recommend use protective gloves.
