What are Ferrite Magnets?
Ferrite magnets are also called ceramic magnets and have been the subject of research since the 20th century. The main component of ferrite magnets is iron oxide (Fe2O3). Strontium or barium ferrite make up the rest of the magnetic mass.
Ferrite magnets are axially magnetized, which means that the north and south poles are on opposite sides of a horizontal line. In diametrically magnetized magnets, however, the north and south poles would be on opposite sides of a vertical line.
Visually, ferrite magnets can be recognized by their black color and by the fact that, unlike neodymium magnets, they are not coated with an alloy.
