What happens to the induced current when the magnetic field through a loop is increased?
  1. The induced current flows in a direction to oppose the increase
  2. The induced current flows in the same direction as the increase
  3. The induced current becomes zero
  4. The induced current fluctuates

Questions & Step-by-Step Solutions

What happens to the induced current when the magnetic field through a loop is increased?
  • Step 1: Understand that a loop of wire can have a magnetic field passing through it.
  • Step 2: Recognize that when the magnetic field strength increases, it changes the amount of magnetic flux through the loop.
  • Step 3: Remember Lenz's law, which states that the induced current will flow in a direction that opposes the change in magnetic flux.
  • Step 4: Conclude that the induced current will flow in a direction that tries to reduce the increase in the magnetic field.
