1. An electric power transmitting device comprising:

  • a first coil;

    a second coil which can be combined with said first coil to provide an inductive coupling therebetween;

    means for supplying a current which is variable in magnitude with time to said first coil to induce an electric current across said second coil through said inductive coupling;

    one of said first and second coils having a bent portion extending along the axial direction of one of the coils;

    the other of said first and second coils being insertable into said one of the coils through said bent portion; and

    the arrangement being such that said first and second coils can be disposed in substantially one plane, and said other of the coils can be moved into and out of said one of the coils in the axial direction of said one of the coils and in a direction transverse to said axial direction.
