Title: Permeability measuring instrument and method
Inventor: SENDA MASAKATSU
IPC: G01R33/12
Filed: 1992-05-25
Abstract: PURPOSE:To measure the absolute value of permeability of an entire magnetic body specimen even in a specific high-frequency band or higher by aligning the magnetic body on the surface of a conductor. CONSTITUTION:A stripe magnetic body 1 is adhered and placed on the surface of a conductor 2 so that it surrounds the periphery of the conductor 2, or the stripe magnetic body 1 is placed on the surface of the conductor 2 so that it sandwiches the conductor 2. The permeability of the magnetic body 1 is measured while the magnetic body 1 is placed on the surface of the conductor. Therefore, since the resonance frequency of an element can be increased to several GHz or higher by the permeability measuring instrument and the permeability measuring method and the value of the permeability can be obtained analytically, the absolute value of the permeability of the entire magnetic body specimen can be measured at a high-frequency region above 100MHz.
