At $795, the Rega Nd7 is the world's first phono cartridge to use ultra-high powered Neodymium magnets in a moving magnet ...

This is due to their relatively low Curie point, which is the temperature above which a substance loses its magnetic properties. At room temperature, a pure bar of neodymium wouldn’t be a magnet ...

Two researchers who independently developed the neodymium magnet — used in everything from hard disk drives to automobiles — have been awarded the 44th Honda Prize. In 1982, two researchers ...

The two types of rare-earth magnets classified according to the materials which the magnets are made of are Samarium-cobalt and Neodymium magnets. Samarium-cobalt magnets were the first family of rare ...

【Fridge Magnets】 The package contains 120 pcs small round magnets of the same size. These fridge magnets quantity are enough to meet your multiple uses. Our refrigerator magnets leave no marks ...

But rather than using alternating currents through large inductors, [Tim] put 40 neodymium magnets with alternating polarity around the circumference of a large MDF disk. When driven by a drill ...

Common magnet materials for industrial magnets include, NdFeB (Neodymium Iron Boron), SmCo (Samarium Cobalt), Ceramic (Ferrite), AlNiCo (Aluminum-Nickel-Cobalt), and Iron-Chromium-Cobalt. The two most ...

It said the "neodymium or 'super strong' rare-earth magnets are sold as toys, decorative items and fake piercings, and are becoming increasingly popular". It added that unlike traditional ones ...

Converting a magnet to a non-magnet is called demagnetisation. Magnets are made from magnetic metals – iron, nickel and cobalt. These are the only pure metals that can be turned into a magnet.

They can be found in the LEDs, magnets, electric motors ... You can identify a rare earth element from its long, complicated name, such as dysprosium or neodymium. Some are abundant, while others are ...
