Chapter 22 WebLab#1 “Faraday’s Law of Induction” Part One * Go to the following website: http://micro.magnet.fsu.edu/electromag/java/transformer/ * Adjust the number of coils in the primary winding, and observe the affect on the output voltage. * Adjust the number of coils in the secondary winding, and observe the affect on the output voltage. Questions: 1)The input voltage alternates according to the sine wave shown. That means that the current also oscillates like a sine wave. With this in mind, describe the magnetic field in the primary winding (and in the big iron donut). 2)In the simulation, how can you increase the strength of the magnetic field created in the primary winding? When you do this, what other quantities describing the primary winding are increased? 3)Your answer to #1 causes a voltage to be created or “induced” in the secondary winding. How can this voltage be increased? Part Two * Go to the following website:
