13.35: For the figure shown, the var w9ldpei 1ya o+55 ien*iabl ql(, 11re uyvyrk+bto u-hu+/e resistance of the innercircuit $R_{inner}$ is increasing at a constant rate. While this isoccurring, in which direction is the magnetic field associated with the inner circuit at the point P in the plane of the circuitand in which direction is the flow of electrons through the resistor labeled $R_{outer}$?
A. Magnetic Field at P is There is no field Electron flow through$R_{outer}$ is There is no flow
B. Magnetic Field at P is Into the page Electron flow through$R_{outer}$ is From Y to X
C. Magnetic Field at P is Into the page Electron flow through$R_{outer}$ is From X to Y
D. Magnetic Field at P is Out of the page Electron flow through$R_{outer}$ is From Y to X
E. Magnetic Field at P is Out of the page Electron flow through$R_{outer}$ is From X to Y
