Unformatted text preview: 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). Because the current is oscillating, the magnetic field is also constantly changing direction, oscillating. 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? By increasing the number of coils in the primary winding. When you do this, the number of magnetic field lines through By increasing the number of coils in the primary winding....
