A uniform magnetic field is perpendicular to the plane of a wire loop. If the loop accelerates in the direction of the field, will a current be induced in the loop? Explain why or why not.
Homework Answers
concept used : current is induced when magnetic flux through the loop increases
now when loop accelerates in the direction of filed, then its speed increases but as magnetic field is uniform and area of loop is fixed and orientation of loop with respect to magnetic field does not changes so magnetic flux does not changes and remains fixed so no current is induced.
answer is NO
