A coil of wire is formed of many loops. These loops, though tracing a circular path, may be though of as being parallel to each other. We know that whenever parallel wires carry and electric current, there will be a mechanical force generated between those two wires.
When electric current is passed through a coil of wire, does the inter-loop force tend to compress the coil, or extend it? Explain your answer.
