Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They retain their magnetic properties even under external field action,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet turns out to be 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...
- Thanks to flexibility in shaping and the capacity to modify to unusual requirements,
- Significant place in advanced technology sectors – they serve a role in hard drives, brushless drives, advanced medical instruments, as well as complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price 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 it depends on?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ground contact surface
- without any insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Clearance – existence of any layer (rust, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached 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).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Respect the power
Handle with care. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.
Flammability
Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Keep away from computers
Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Eye protection
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them shattering into shards.
Crushing force
Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Allergic reactions
A percentage of the population have a contact allergy to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause an allergic reaction. We recommend wear protective gloves.
Phone sensors
Be aware: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.
Swallowing risk
Adult use only. Tiny parts pose a choking risk, causing serious injuries. Store away from kids and pets.
Implant safety
Patients with a heart stimulator should keep an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
Heat sensitivity
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.
