When the magnet is moved toward the stationary conducting loop, a current is induced in the loop in the direction shown. The magnetic field lines are due to the bar magnet. When the magnet is moved away from the stationary conducting loop, a current is induced in the loop in the This induced current in This induced current in the the loop produces its own magnetic field directed to the left that counteracts the loop produces a magnetic field directed to the right and so counteracts the increasing external flux. direction shown. decreasing external flux. N N a Figure 30.13 (Conceptual Example 30.4) A moving bar magnet induces a current in a conducting loop.
