A student investigates electromagnetic induction by moving a flat rectangular coil of wire at a constant horizontal speed through a region of uniform magnetic field. The coil is connected to a sensitive center-zero galvanometer.
The diagram shows three consecutive stages of this experiment:
Which row in the table correctly describes the deflection shown on the galvanometer pointer for each of the three stages?
| Stage X (Coil entering field) | Stage Y (Coil fully inside field) | Stage Z (Coil exiting field) | |
|---|---|---|---|
| A | Deflects to the left | Remains at zero | Deflects to the right |
| B | Deflects to the right | Remains at zero | Deflects to the left |
| C | Deflects to the right | Remains at zero | Deflects to the right |
| D | Deflects to the right | Deflects to the left | Deflects to the left |
Stage X: Deflects to the left | Stage Y: Remains at zero | Stage Z: Deflects to the right
Stage X: Deflects to the right | Stage Y: Remains at zero | Stage Z: Deflects to the left
Stage X: Deflects to the right | Stage Y: Remains at zero | Stage Z: Deflects to the right
Stage X: Deflects to the right | Stage Y: Deflects to the left | Stage Z: Deflects to the left
