Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They retain attractive force for almost 10 years – the loss is just ~1% (based on simulations),
- Neodymium magnets are highly resistant to magnetic field loss caused by external field sources,
- Thanks to the metallic finish, the surface of nickel, gold, or silver gives an aesthetic appearance,
- Magnetic induction on the surface of the magnet remains strong,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the possibility of accurate molding and customization to custom projects, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Versatile presence in high-tech industry – they are utilized in HDD drives, brushless drives, diagnostic systems, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in miniature devices
Limitations
- At very strong impacts they can break, therefore we recommend placing them in special holders. 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 force. 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- characterized by even structure
- without the slightest clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.
H&S for magnets
Power loss in heat
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Do not drill into magnets
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Data carriers
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Medical interference
Patients with a heart stimulator should maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
Allergy Warning
It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact or choose encased magnets.
Bodily injuries
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Magnetic interference
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, device, and GPS.
Material brittleness
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Choking Hazard
Absolutely store magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.
Immense force
Use magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their power.
