Question
When a current-carrying coil C2 is moved towards a coil C1 connected in series with a galvanometer, the pointer in the galvanometer G:
- Shows deflection while C2 is stationary
- Oscillates
- Shows deflection while C2 is in motion
- Does not move
Hint:
When a current-carrying coil C1 is connected to coil C2, the deflection in a galvanometer can be measured when the C2 is in motion.
The correct answer is: Shows deflection while C2 is in motion
When a current-carrying coil C2 is moved towards a coil C1 connected in series with a galvanometer, the pointer in the galvanometer G shows deflection when the C2 is in motion.
- The galvanometer is used to detect a small amount of current change.
- It shows deflection when there is a motion in the current flow.
- If the current-carrying coil C1 is moved towards the C2 coil, it shows deflection in the galvanometer when the C2 is in motion.
- This indicates that electric current is induced in coil C1.
- When C2 is moved away, the galvanometer shows a deflection again, but this time in the opposite direction.
