Consider a single current loop (Fig. 20.35) carrying a current I. It represents one loop of a solenoid. The magnetic field from one part of the loop will lead to a magnetic force on other parts of the loop. Will these magnetic forces tend to (a) make the loop collapse, (b) make the loop explode, or (c) have no effect?
