- Electromagnetic Induction Experiment In This Experiment The Activity Will Be Based On A Phet Simulation Called Faraday 1 (80.09 KiB) Viewed 33 times
Part 4 - Transformer - Use the fourth tab to switch to the Transformer simulation This shows an electromagnet magnet near a pickup coil. The pickup coil can be connected to a light bulb or a voltmeter. For now, leave the coil connected to the light bulb. Note that you can click-and-drag to move the electromagnet, or you can click-and-drag to move the light bulb. In this simulation, there are at least six ways to get the light bulb to light up briefly, in the DC situation. List the methods you come up with to light the bulb. It might help to place the pickup coil so the coil for the electromagnet is inside the pickup coil.

You should be able to make the meter go from its maximum positive reading to its maximum negative reading and back. Describe everything you have to do to cause this to happen. (1 pt) Place the coils so that the coil for the electromagnet is inside the pickup coil. Why is using a larger- area pickup coil is less effective than using a smaller-area pickup coil? (1 pt) Are the charges (blue dots) in the pickup coil in phase with those in the electromagnet? In other words, when the charges in the electromagnet are moving fastest, are the charges in the pickup coil moving fastest? Why or why not? (1 pt)
