14.34: Two circular loops of resistive wire a4khzo.ulve*w qh-d 0smj1k*2 re placed next to each other d;r * lnfp9ni bz)*k(xas in the figure. The circular loop on the left is connected to a constant voltage source V. The resistance of this loop is increasing linearly with time. As the resistance is changing, what is the direction of the magnetic field at point P (the center of the left-hand loop) an)pkn9; f*ibxzr (n *ldd what is the orientation of the conventional current in the right-hand loop (as viewed in the figure from above)?



A. Magnetic Field Direction is Into the plane of the page Current Orientation is Counterclockwise
B. Magnetic Field Direction is Into the plane of the page Current Orientation is Clockwise
C. Magnetic Field Direction is Out of the plane of the page Current Orientation is Counterclockwise
D. Magnetic Field Direction is Out of the plane of the page Current Orientation is Counterclockwise
E. Magnetic Field Direction is There is no field Current Orientation is There is no current
