Ceramic Magnet Wikipedia

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. A ceramic is any of the various hard brittle heat resistant and corrosion resistant materials made by shaping and then firing a nonmetallic mineral such as clay at a high temperature. 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. 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.

Obsolete 9 ghz magnetron tube and magnets from a soviet aircraft radar. 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. They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet. A force that pulls on other ferromagnetic materials such as iron and attracts or repels other magnets.

The magnetic field typically produced by rare earth magnets can exceed 1 4 teslas whereas ferrite or. They are composed of iron oxide and strontium carbonate. Common examples are earthenware porcelain and brick.
