Abstract: The invention of the multiple coupling & non-coupling inductor includes at least an wrapped iron-core assembly and plural conductors where the wrapped iron-core assembly is composed of mutually corresponding magnetic conductors, which lie penetrated grooves on the X-axis & the Y-axis for penetration of plural conductors. Plural conductors provide mutual inductance along the X-axis and the Y-axis but none between the X-axis and the Y-axis to create a structural design of an iron-core assembly with a multiple coupling & non-coupling.
