This bar neodymium rare earth magnet is made of grade N45 rare earth magnetic material and coated with black epoxy. It is very powerful and has about 58 lb holding power. It can be used for magnetic holdings, fishing and separations.
1. All magnets are fragile and may snap when collide into each other or a steel. These are very strong, if not careful, they will break. If handled correctly, they will last for a lifetime.
2. The epoxy coating is softer than ni coating. It is easier to get scratched.
3. When apply the magnet, hold one end of the magnet and let the other end touching the surface and slide onto the surface.
4. Keep it away from pacemakers and children under 5 years old.
New neodymium magnet in hybrid vehicles
This method of neodymium magnet production enables nanometer-scale crystal grains to be aligned to realize a fine crystal grain structure that is approximately ten times smaller than that of a sintered magnet, which makes it possible to produce magnets with greater heat resistance properties.
Honda revised the shape of the magnet to make it fit in the drive motor of its hybrid vehicles while also redesigning the motor and the shape of the rotor to optimize the flow of the magnetic flux of the magnet.
The result is a hot deformed neodymium magnet with no heavy rare earth metal that provides torque and with heat resistance performance similar to a conventional magnet. Customized Multi-stage Magnetization Ferrite Anisotropic Tube Magnet
Honda will use the new hot deformed neodymium magnet on the Honda SPORT HYBRID i-DCD 2 system for the all-new FREED.
Neodymium magnets have the highest magnetic force among all magnets in the world and are being used for the drive motors of electric vehicles including hybrid vehicles, and therefore demand for neodymium magnets are expected to grow exponentially in the future.
For use in the drive motors of electric vehicles, neodymium magnets must have high heat resistance properties as they are used in a high temperature environment. Adding heavy rare earth (dysprosium and/or terbium) to the neodymium magnets has been a conventional method to secure such high heat resistance.
