Answer Posted / satendra
On increasing the voltage the current will also be increase (as the res. is constant)in turn flux will also be increase.
But after the saturation point on increasing the voltage the current will go infinite momently. This point is called KNEE-POINT. After the knee point there are a more chances to get the coil as a permanent magnet. So we never perform the test upto knee-point.
