Question: What is the direction of the induced current when a magnet is moved towards a coil?

Options:

  1. Clockwise
  2. Counterclockwise
  3. No current
  4. Depends on the magnet\'s polarity

Correct Answer: Counterclockwise

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.

Questions & Step-by-Step Solutions

What is the direction of the induced current when a magnet is moved towards a coil?
  • 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.
