Q: What happens to the induced current when the magnetic field is removed from a closed loop?

Solution: When the magnetic field is removed from a closed loop, the induced current stops immediately as there is no longer a changing magnetic flux.

Steps: 5

Step 1: Understand that a closed loop can have a magnetic field passing through it.
Step 2: Know that when the magnetic field changes (like when it is removed), it creates a change in magnetic flux.
Step 3: This change in magnetic flux induces a current in the loop according to Faraday's law of electromagnetic induction.
Step 4: When the magnetic field is completely removed, there is no longer any change in magnetic flux.
Step 5: Since there is no change in magnetic flux, the induced current stops immediately.
