Ceramic Magnet Wikipedia

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.

Ceramic magnet wikipedia. 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. 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. 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.

Common examples are earthenware porcelain and brick. Obsolete 9 ghz magnetron tube and magnets from a soviet aircraft radar. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. 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.

The magnetic field typically produced by rare earth magnets can exceed 1 4 teslas whereas ferrite or. A force that pulls on other ferromagnetic materials such as iron and attracts or repels other magnets. 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.
