2.Electric current is induced in the coil when the ___________ changes. *
Answers
Answer:
Current is induced in a coil by electromagnetic induction when coil and the magnet move with respect to each other.
Answer:
Magnet and coil move in respect to each other
Explanation:
Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. It is the production of an electric current by changing the magnetic field enclosed by an electrical circuit.
It is a process where a conductor, say a coil, placed in a changing magnetic field, say close to a bar magnet, (or a conductor moving through a stationary magnetic field) causes the production of a voltage across the conductor. This process of electromagnetic induction, in turn, causes an electrical current - it is said to induce the current.
Current is induced in a coil by electromagnetic induction when coil and the magnet move with respect to each other.
