A flat circular conductive loop lies in the xyxyxy-plane, centered at the origin within a uniform magnetic field B⃗\vec{B}B pointing in the positive yyy-direction.
The loop always remains entirely within the magnetic field. Four possible actions are performed on the coil:
- translating the loop horizontally along the xxx-axis
- rotating the loop about Axis 1 (the xxx-axis)
- rotating the loop about Axis 2 (the yyy-axis)
- rotating the loop about Axis 3 (the zzz-axis, perpendicular to the plane of the loop and passing through its center)
How many of these actions will result in an induced electromotive force (emf) in the loop while the action is occurring?
