A square loop `ABCD` of edge a moves to the right with a velocity `v` parallel to `AB` . There is a uniform magnetic field of magnitude `B` , direction into the paper, in the region between `PQ` and `RS` only. I, II and III are three ppositions of the loop.
(i) The emf induced in the loop has magnitude `B` a `v` in all three position
(iii) Induced emf is anticlockwise in position II
(iv) The induced emf is clockwise in position III

Options

A. the emf induced in the loop has magnitude in all three positions
B. the induced emf is zero in position II
C. the induced currents is anticlockwise in position I
D. the induced current is clockwise in position III.

Answer

B, C, D
