In a particular problem, a circular loop of wire is placed in a magnetic field facing downwards(x) or away from the page. In the first second, the magnetic field changes by -1.2 T/s. What is the direction of the current induced ? My reasoning goes as follows - As the rate of change of field is -ve, the final field is < initial field. Thus, by Lenz'law, the direction of induced current must be in the same direction as the existing field to strengthen the existing field. So, as per given data, the current must flow clockwise. But the book says it must be counterclockwise. Am I missing something here? Thanks!
