Question 3
Six loops are formed of copper wire of the same cross-sectional area. Loops and are identical, loop has the same area as the others but is longer. At the instant shown, all the loops are moving at the same speed in the directions indicated. A uniform and constant magnetic field points out of the page in region , in region there is no magnetic field. Ignore any interaction between the loops.

The correct order of magnitudes of emf induced in the loop is
