In general, magnets describe any materials that can attract ferromagnetic objects. These ferromagnetic objects include iron, nickel, cobalt, and so many others. Magnets produce magnetic fields, which are responsible for their ability to attract ferromagnetic objects. Although magnetic fields are invisible, their presence can be detected via the magnetic force they exert. Permanent magnets are

How Are Ferrite Magnets Made?
How Are Ferrite Magnets Made? Ferrite magnet, also know as a ceramic magnet, is a kind of permanent magnet. Compared with other permanent magnets, ferrite magnets are hard and brittle and have lower magnetic energy. But it is not easy to demagnetize, not easy to be corroded, and low in price. Therefore, ferrite magnets are widely used
