A closed loop of vecB is produced by a changing electric field. Does it necessarily mean that vecE and dvecE//dt are non-zero at all points on the loop and in the area enclosed by the loop? |

Answer» Solution :Non necessarily. The basic requirement is that the TOTAL electric flux through the area ENCLOSED by the loop should very with time. The flux change may arise form any portion of the area. Elsewhere E or dE/dt may be ZERO. In particular, there NEED be no electric FIELD at points which make the loop. |
