in case of electromagnetic induction what causes the flow of current through the coil
Answers
Answer:
Explanation:
Electromagnetic induction is caused when a current carrying conductor is exposed to a varying magnetic field.
On switching on the current, a current is started in a wire held near a loop of wire. This change in the current causes a change in the magnetic field and hence the phenomenon of electromagnetic induction is observed in the loop of wire.
On switching off the current, a current is stopped in the wire held near a loop of wire. This change in the current causes a change in the magnetic field and hence the phenomenon of electromagnetic induction is observed in the loop of wire.
When a magnet is moved through a loop of wire, there is a change in magnetic field lines through the coil. This change in magnetic field again causes electromagnetic induction in the coil.
