Aim:
To observe the generation of an electric watercourse as a wire is cut by a attractionic expanse verifying Lenzs law.
Materials:
Solenoid (1 large of 500 turns, 1 small of 250 turns)
Galvanometer
Wires
Rectangular leave out Magnets
Procedure:
The Solenoid, Galvanometer and wires were arranged in series to create a circuit. star determination of the draw was then thrusted in to an open end of the solenoid (B1), held still (B2), then removed (B3) and the magnitude and direction of the accredited produced was noted at each of these three stages. The end of the magnet was then noted to be North and it was thrusted into the solenoid and the direction current was noted, the polarity of the solenoid was then determined (B4). The number of magnets and number of turns in the solenoid were then varied and the results were recorded accordingly (C1, C2). The magnet was the held nonmoving inside the solenoid and the solenoid was spun around the magnet and results were recorded once once more (C4).
Data:
B1) ban current was produced therefore no reading
B2) No current
B3) 7mA
B4) Negative Current
C1)
        250 turn solenoid         500 turn solenoid
1 magnet         7mA         11mA
2 magnets         10mA         20mA
C2) It appears that the number of coils in the solenoid is directly proportional to the current produced.
C3) One magnet - Solenoid of 750 turns.
                                slack off                 Fast
Current produced                 6mA                 15mA
C4) No current.
Analysis:
From the fact that a current is only produced when the magnet inside the solenoid is moving (B1, B2, B3), it is apparent that there is a kindred between the movement of the magnetic field and the current induced. It too became apparent that as the magnet was inserted in to the end of the...
