Part 3 - Electromagnet Now, use the third tab at the top of the simulation window to switch to the Electromagnet simulation. In the menu at the right, check all the checkboxes, which gives both a compass and a field meter on the screen. Here, instead of a bar magnet, we have an electromagnet - a magnetic field is created by setting up a current in a coil. Start with the DC case, in which a battery is connected to the coil. DC, by the way, stands for _. (1 pt) In this situation, what is the magnitude of the maximum magnetic field that can be achieved? Where is that maximum field located? (1 pt) 2 of 4 Name: Section #: Compare the magnetic field created by the electromagnet (in the DC case) to the magnetic field created by a bar magnet. Think about the case of a short stubby bar magnet, the same size as the coil. Do the electromagnet and the same-size bar magnet create similar fields? Identical fields? Completely different fields? Explain. (1 pt) In the DC case, can we change the magnitude of the magnetic field at a particular point without moving the coil? Explain. (1 pt) Now, switch to AC, which stands for (1 pt) For the AC situation, you see a graph. What is this a graph of? (1 pt) On the vertical axis of the graph is ... On the horizontal axis of the graph is ... What does the magnetic field do with the coil connected to the AC source? (1 pt)
