Question 121

The magnetic flux Φ\PhiΦ through a single-turn coil varies with time ttt as follows:

  • From t=0 st = 0\text{ s}t=0 s to t=2 st = 2\text{ s}t=2 s, the flux is constant at 6.0 Wb6.0\text{ Wb}6.0 Wb.
  • From t=2 st = 2\text{ s}t=2 s to t=5 st = 5\text{ s}t=5 s, the flux decreases linearly from 6.0 Wb6.0\text{ Wb}6.0 Wb to 0 Wb0\text{ Wb}0 Wb.
  • From t=5 st = 5\text{ s}t=5 s to t=7 st = 7\text{ s}t=7 s, the flux remains constant at 0 Wb0\text{ Wb}0 Wb.
  • From t=7 st = 7\text{ s}t=7 s to t=8 st = 8\text{ s}t=8 s, the flux increases linearly from 0 Wb0\text{ Wb}0 Wb to 6.0 Wb6.0\text{ Wb}6.0 Wb.

Determine the induced electromotive force (emf), E\mathcal{E}E, in the coil during each of these four time intervals.
