A ferrite is a ceramic material made by mixing and firing large proportions of iron iii oxide fe 2 o 3 rust blended with small proportions of one or more additional metallic elements such as barium manganese nickel and zinc. A force that pulls on other ferromagnetic materials such as iron and attracts or repels other magnets. A magnet is a material or object that produces a magnetic field this magnetic field is invisible but is responsible for the most notable property of a magnet. What is a ceramic magnet ceramic magnets also known as ferrite magnets were developed in the 1960 s as a low cost alternative to metallic magnets.

While their hard brittle quality and low energy exclude them from some applications ceramic magnets have won wide acceptance due to their corrosion and demagnetization. The crystallinity of ceramic materials ranges from highly oriented to semi crystalline vitrified and often completely amorphous e g glasses. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. The tube is embraced between the poles of two horseshoe shaped alnico magnets top bottom which create a magnetic field along the axis of the tube the microwaves are emitted from the waveguide aperture top which in use is attached to a waveguide conducting the microwaves to the radar antenna.

The magnetic field typically produced by rare earth magnets can exceed 1 4 teslas whereas ferrite or. Obsolete 9 ghz magnetron tube and magnets from a soviet aircraft radar. They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet.
