A single circular loop of wire in the plane of the page is perpendicular to a uniform magnetic field B, directed out of the page as shown above.
If the magnitude of the magnetic field is decreasing, then the induced current in the wire is:
Clockwise round the loop.
Anticlockwise round the loop.
Counter clockwise around the loop.
Directed upwards out of the paper.
