Question

A long, straight, current-carrying wire passes near a wire loop. The current in the straight wire is directed to the right, and its magnitude is decreasing. a) What is the direction of the magnetic flux through the loop? 1. Pointing towards the left 2. Pointing into the plane of the figure ____________________ b) Is the magnitude of the flux through the loop increasing or decreasing with time? 1. Decreasing 2. Increasing ____________________ c) What is the direction of the magnetic field produced by the induced current in the loop? 1. Pointing into the plane of the figure 2. Pointing out of the plane of the figure 3. Pointing towards the right 4. Pointing towards the left ____________________ d) What is the direction of the current induced in the loop? 1. Clockwise 2. Anti-clockwise ____________________ e)The induced current leads to a magnetic force on the loop. What is the direction of the force? 1. Towards the wire 2. Away from the wire ____________________
