... These resistors utilize high quality resistance wire wound on a ceramic core, terminated, and finished with our flameproof Centohm® coating. Ohmite’s Audio Gold resistors have been carefully engineered with non-magnetic materials to eliminate the effects of these stray magnetic fields on circuit per ...
General Properties of Magnets
... Materials which can be easily magnetized are known as ferromagnetic. Examples of ferromagnetic materials include iron, nickel and cobalt. If any of these metals are placed inside a magnetic field, they can become magnetized (induced). They can also be used to create electromagnets by placing them wi ...
