Case : Read the passage and answer the question(s). Let us consider a straight conductor moving in a uniform and time-independent magnetic field. Figure shows a rectangular conductor PQRS in which the conductor PQ is free to move. The rod PQ is moved towards the left with a constant velocity v as shown in the figure. PQRS forms a closed circuit enclosing an area that changes as PQ moves. The length RQ = x and RS = l and the magnetic flux is ΦB enclosed by the loop PQRS. |
What kind of field is provided for the phenomenon to occur? |
Varying Electric Varying Magnetic Constant Electric Constant Magnetic |
Constant Magnetic |
Given in the statement that the field is uniform and time-independent. |
