Advantages as well as disadvantages of rare earth magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They maintain their magnetic properties even under strong external field,
- By applying a decorative layer of silver, the element presents an aesthetic look,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- In view of the option of accurate shaping and customization to specialized solutions, NdFeB magnets can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Universal use in modern industrial fields – they find application in HDD drives, drive modules, advanced medical instruments, and complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these devices are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension is min. 10 mm
- with a plane perfectly flat
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Determinants of lifting force in real conditions
- Gap (betwixt the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Load vector – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Material brittleness
NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them shattering into small pieces.
Crushing risk
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
Compass and GPS
Remember: neodymium magnets produce a field that confuses precision electronics. Keep a safe distance from your mobile, tablet, and GPS.
Avoid contact if allergic
A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact can result in an allergic reaction. It is best to wear safety gloves.
Magnetic media
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.
No play value
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.
ICD Warning
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Power loss in heat
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Mechanical processing
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Immense force
Handle magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.
