Abstract

PURPOSE:To increase inductance, by filling a conductor space where magnetic flux posible makes a small loop with low-permeable material. CONSTITUTION:Conductive coils 18, 19 are buried in a magnetic portion. The conductive coil is filled with an insulative, low-permeable material 20. This constitution makes only magnetic flux phi3, because high-magnetic resistance of the material 20 prevents the magnetic flux from making a small loop, thereby increasing the inductance value at the desired portion.
