Advantages as well as disadvantages of rare earth magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- In other words, due to the shiny finish of gold, the element becomes visually attractive,
- 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...
- In view of the potential of free shaping and adaptation to unique solutions, NdFeB magnets can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
- Universal use in future technologies – they are commonly used in HDD drives, electric drive systems, diagnostic systems, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices
Cons
- At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of making nuts in the magnet and complex shapes - recommended is a housing - magnet mounting.
- Potential hazard resulting from small fragments 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 devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with a surface free of scratches
- without any insulating layer between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be wasted to the other side.
- Plate material – mild steel attracts best. Alloy steels reduce magnetic properties and holding force.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Metal Allergy
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop working with magnets and use protective gear.
Heat warning
Avoid heat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Threat to navigation
GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Handling guide
Handle with care. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can react.
Adults only
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.
Medical implants
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Physical harm
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Fire warning
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Eye protection
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Cards and drives
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
