Description : What is the direction of the induced electric field?
Answer : It is in opposite direction to the one that produced it.
Description : How can we increase the induced current?
Answer : Induced current can be increased by reducing no of windings on the secondary part compared to primary.
Description : What happens when you reverse the direction of the current in an electromagnet?
Answer : When you reverse current direction in an electromagnet, the magnetic poles will also change.
Description : What is the direction of an AC current?
Answer : The magnitude and direction of alternating current is changes with respect to time. So for half cycle it is positive and for next half cycle it is negative.
Description : What is the direction of flow of current?
Answer : Current flows from anode to cathode(opposite direction to flow of electrons)
