MCQ
Refer to the figure. When does the the galvanometer $(G)$ deflect?
- ✓The magnet is pushed into the coil
- BThe magnet is rotated into the coil
- CThe magnet is stationary at the centre of the coil.
- DThe number of turns in the coil is reduced.
✓
Answer
Correct option: A.
The magnet is pushed into the coil
The deflection in the galvanometer $(G)$ occurs, when the magnet is pushed into the coil. This is because the relative motion between the two induces an emf into the coil.
