Advantages and disadvantages of neodymium magnets.
Advantages
- They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by external field sources,
- By covering with a reflective layer of gold, the element gains an elegant look,
- Magnets have huge magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Considering the possibility of precise molding and adaptation to unique requirements, neodymium magnets can be created in a broad palette of shapes and sizes, which amplifies use scope,
- Huge importance in modern industrial fields – they find application in HDD drives, electromotive mechanisms, diagnostic systems, as well as technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- 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 strength. 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- 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?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ground touching surface
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Magnetic interference
Note: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your phone, device, and navigation systems.
Pinching danger
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Heat warning
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Product not for children
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from children and animals.
Handling rules
Handle with care. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.
Safe distance
Avoid bringing magnets near a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Do not drill into magnets
Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Medical interference
Individuals with a ICD must keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets will cause them breaking into shards.
Skin irritation risks
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.
