Straight Wire

If a current is flowing through a straight wire, this generates a magnetic field that is radially symmetric around said wire and is easier to study than a wire of arbitrary shape. For instance, the magnetostatic force between two parallel wires is linearyly proportional to the currents that flow through them, which is similar to the formula for the electrostatic force between two charges (the only difference is in the power which the distance between them is raised to).
