Question
When a magnet M is pushed in and out of a circular coil C connected to a very sensitive galvanometer G as shown in fig.
- Deflection will be observed in the galvanometer when the magnet is moved in and out of the coil
- No flux changes in the coil during the motion of the magnet
- Change in the deflection will be observed when the magnet is at rest.
- No variation in the galvanometer
Hint:
The galvanometer is an instrument used to detect a small amount of current flow, when the magnet moves in and out of the coil.
The correct answer is: Deflection will be observed in the galvanometer when the magnet is moved in and out of the coil
When a magnet M is pushed in and out of a circular coil C connected to a very sensitive galvanometer G, deflection will be observed in the galvanometer when the magnet is moved in and out of the coil
- The galvanometer is an instrument used to detect the direction and magnitude of current flow.
- When a magnet is pushed in and out of a coil, there will be a magnetic field that is continuously changing.
- This movement of constant deflection can be measured using the galvanometer.
