Practical Experiment report proving Lenz Law.

Aim: To observe the generation of an electric current as a wire is cut by a magnetic field verifying Lenz's law. Materials: Solenoid (1 large of 500 turns, 1 small of 250 turns) Galvanometer Wires Rectangular Bar Magnets Procedure: The Solenoid, Galvanometer and wires were arranged in series to create a circuit. One end of the magnet was then thrusted in to an open end of the solenoid (B1), held still (B2), then removed (B3) and the magnitude and …showed first 75 words of 641 total…

Conclusion: Throughout this experiment, Lenz Law was apparent. The movement of a magnetic field inside a solenoid induces an electric current. If the experiment were to be conducted again, more advanced equipment would produce certainly much more accurate and consistent data. (Spaces left are for hand drawn diagrams)
