Answer: C
Explanation:
The flux due to the loop always opposes the change in the flux due to the external magnetic field. This occurs as a result of the current that is induced in a coil (due to a magnetic flux change through the coil) which will always be in such that it opposes the change that caused it. ... Any induced current in a coil will result in a magnetic flux that is opposite to the original changing flux. This was what Faraday was explaining in the law of Induction
