An alternating current can induce voltage because it has
ripple value
varying magnetic field
weaker magnetic field than direct current
high peak value
Correct answer is B
As induced voltage is produced by varying magnetic field. The induced voltage is proportional to the rate of change of magnetic flux linking the coil.
