  • Method and apparatus for measuring magnetic properties of magnetic materials using positive and negative magnetic saturation of the materials
    Patent number: 4623841
    Abstract: A piece of the magnetic material to be tested is coupled to the device by primary and secondary windings. The material is then exposed to varying polarities of a controlled electrical current, such as a ramped current, through the primary winding causing the magnetic flux of the material to vary with respect to the controlled current; and creating varying voltage levels across the secondary winding. When this process has been completed the data is made available to a computer which now has data for the current levels transmitted through the primary winding and the corresponding voltage levels across the secondary winding. The computer can then utilize this data to provide a variety of magnetic property values of the magnetic material.
