If you pass a current through a wire, you can create a magnetic field. In this class we examine the field from three specific configurations: an infinitely-long straight wire, a compact loop of wire (possibly with multiple turns, a coil), or an infinitely long solenoid (think of an infinitely-long cylinder of loops made by wrapping a single wire). See the text for an extended description of all three geometries. Here’s the challenge: there are three slightly different formulas used to...
