What is the direction of the induced current when a magnet is moved towards a coil?
Clockwise
Counterclockwise
No current
Depends on the magnet's polarity
According to Lenz's law, the induced current will flow in a direction that opposes the change, which is counterclockwise if the magnet is moved towards the coil.

Q: What is the direction of the induced current when a magnet is moved towards a coil?
Solution: According to Lenz's law, the induced current will flow in a direction that opposes the change, which is counterclockwise if the magnet is moved towards the coil.
Steps: 5
Step 1: Understand that when a magnet moves towards a coil, it creates a change in the magnetic field around the coil.
Step 2: Remember Lenz's law, which states that the induced current will flow in a direction that opposes the change in magnetic field.
Step 3: Visualize the situation: as the magnet approaches, the magnetic field inside the coil increases.
Step 4: To oppose this increase, the coil will generate a current that creates a magnetic field in the opposite direction.
Step 5: Determine the direction of the induced current: if the magnet is moving towards the coil, the induced current will flow counterclockwise when viewed from the magnet's side.
