Now that you’ve verified there’s current through the electromagnet, uncheck the Show Electrons box. This action turns off the electrons. (The current is still there; we just don’t see it.) Check the Show Compass box. Move the compass to the bottom right side of the coil. Does the electromagnet affect the compass needle?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
