1. A current controlled variable inductor, comprising:

  • a magnetically saturable core further comprising opposed outer limbs having a substantially uniform cross section each joined to a center limb by connecting limbs, wherein a staggered;

    series of flux bridges and air gaps are formed on spaced intervals along the outer limbs;

    an electrically conductive insulated bias winding wound on the center limb for magnetically coupling a bias current to vary the inductance of the inductor; and

    an electrically conductive insulated signal winding wound on the outer limbs for magnetically coupling a signal current to the inductor.
