Problem: The sketch shows the coil lying in the plane of the screen and the external magnetic field pointing into the screen. As the external magnetic field decreases, an induced current flows in the coil. (a) What is the direction of the induced magnetic field caused by this current?(b) What is the direction of the induced current in the wire shown in the picture?A. clockwiseB. counterclockwise

(a)

According to Lenz's law, the induced magnetic field opposes the change in magnetic flux causing it. 

The induced magnetic field will strengthen the decreasing magnetic field.
