Abstract
A current variable inductor having closed loop characteristics and a horizontal linearity compensation circuit. The current variable inductor having the closed loop characteristics is constructed with the legs of the first E-shaped core and the legs of the second E-shaped core extend toward each other, an I-shaped core is arranged between the first E-shaped core and the second E-shaped core such that the I-shaped core is in contact with the first E-shaped core, and the I-shaped core is spaced apart from the second E-shaped core. A primary coil is wound around a center leg of the first E-shaped core and a secondary coil is wound around a center leg of the second E-shaped core. A magnetic flux generated from the primary coil is cut due to the magnetic resistance characteristics of the I-shaped core to vary the inductance of the secondary coil, to thereby form enclosed loops of magnetic flux inside the first and second E-shaped cores, respectively.
