Question
  1.   A conductor moves with a velocity of 15 m/s at an angle of (a) 90◦, (b) 60◦ and (c) 30◦ to a magnetic field produced between two square-faced poles of side length 2 cm. If the flux leaving a pole face is 5 µWb, find the magnitude of the induced e.m.f. in each case.
  2. Replace the delta-connected network shown in shown in Fig 1.0 by an equivalent star connection.

  3. Determine the e.m.f induced in a coil of 200m turns when there is a change of flux of 25mWb linking it in 50ms.
