Practical Experiment report proving Lenz Law.

Aim: To observe the generation of an electric watercourse as a wire is cut by a attractionic sweep verifying Lenzs law. Materials: Solenoid (1 large of 500 turns, 1 small of 250 turns) Galvanometer Wires orthogonal leave out Magnets Procedure: The Solenoid, Galvanometer and wires were arranged in series to create a circuit. star determination of the draw was then(prenominal) thrusted in to an open end of the solenoid (B1), held still (B2), then outside (B3) and the magnitude and direction of the accredited produced was noted at distributively of these three stages. The end of the attractor was then noted to be North and it was thrusted into the solenoid and the direction genuine was noted, the polarity of the solenoid was then resolved (B4). The number of magnets and number of turns in the solenoid were then varied and the results were save accordingly (C1, C2). The magnet was the held nonmoving inside the solenoid and the solenoid was spun around the magnet and re sults were recorded once once more (C4). Data: B1) put away period was produced in that respectfore 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 comparative to the current produced. C3) One magnet - Solenoid of 750 turns.

                                    slack off            Â Â Â Â Â Â Â  close 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 topic and the current induced. It too became apparent that as the magnet was inserted in to the end of the... If you sine qua non to get a full essay, assign it on our website: BestEssayCheap.com
