Q: What happens to the induced current if the magnetic field is suddenly removed from a coil? (2022)

Solution: If the magnetic field is suddenly removed, the change in magnetic flux becomes zero, leading to an immediate stop in the induced current.

Steps: 6

Step 1: Understand that a coil can have a magnetic field around it when there is current flowing through it.
Step 2: Know that when the magnetic field is present, it creates magnetic flux in the coil.
Step 3: Realize that induced current is generated in the coil when there is a change in magnetic flux.
Step 4: When the magnetic field is suddenly removed, the magnetic flux in the coil changes quickly.
Step 5: If the magnetic field is completely removed, the change in magnetic flux becomes zero.
Step 6: Since there is no change in magnetic flux, the induced current stops immediately.
