Diagram I, below, shows selected magnetic field lines between opposite poles, point P, and an arrow representing the magnetic field strength at point P. Diagram I N S Diagram Il showws the same magnetic field, the same point P, a current-carrying wire oriented perpendicular to the magnetic field, and the direction of the electron flow in the current- carrying wire. Diagram II N S O Represents electron flow into the page Which of the following diagrams, drawn to the same scale as Diagram I above, represents the net magnetic field strength at point P in Diagram II, if the induced magnetic field due to the electron flow is twice the magnitude of the field strength at point P in Diagram 1? Select one: Oa. P Ob. O d.
