[单选题]
14.34: Two circular b7;/w l9xs xoaloops of resistive wire a ijzei8krrc 6wys e )51iz )*ap:fc68jre placed next to each other as in the figure. The circular loop on the left is connected tj k8yjes6 i crpw)ez1:z*f6c)ia5i8r o 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) and 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
