Need help with Parts A, B, and C for the question below:

A circular loop in the plane of a paper lies in a 0.85 T magnetic field pointing into the paper. The loop's diameter changes from 18.5 cm to 6.6 cm in 0.52 s.

Part A: What is the direction of the induced current?

A. Clockwise

B. Counter Clockwise

Part B: What is the magnitude of the average induced emf?

Part C: What is the average induced current if the coil resistance is 4.1 ?
