G1 Physics · Accepted Answer

Step 1: An electron moving past a stationary conducting loop changes the magnetic flux through its area. Step 2: For approach and recession, the rate and sign of flux change generally reverse, so the induced-current direction reverses. Step 3: The loop current therefore reverses as the electron passes. Answer C. Final answer: (C) The induced current reverses as the electron passes the coil..
