Rajah 10.1 Rajah 10.2

(a) Diagram 10.1 shows a magnet being pushed into a copper wire coil.
Diagram 10.2 shows the same magnet being pulled out from the copper wire coil.
Using Diagram 10.1 and Diagram 10.2, compare the direction of the movement of the magnet, the
number of turns of the wire coil, and the deflection of the galvanometer.
Relate the direction of the movement of the magnet and the deflection of the galvanometer.
Hence, deduce a physics law.
Rajah 10.1 menunjukkan satu magnet ditolak ke dalam satu gegelung dawai kuprum.
Rajah 10.2 menunjukkan magnet yang sama ditarik keluar daripada gegelung dawai kuprum
tersebut. Dengan menggunakan Rajah 10.1 dan Rajah 10.2, bandingkan arah pergerakan magnet,
bilangan lilitan gegelung dawai, serta pesongan galvanometer. Hubungkaitkan arah pergerakan
magnet dengan pesongan galvanometer.
Dengan itu, deduksikan satu hukum fizik.
