- A long straight wire is fixed in space and has current I. Draw the wire vertically with the current flowing upward. A square wire loop with side length s and resistance R is in the plane of the page and has its closest side a distance x away from the wire. Find the magnetic flux through the square HINT: The B-field depends on distance from the wire so you will have to integrate. The loop is pushed with velocity v toward the Find the rate of change of magnetic flux. HINT: Don't forget the chain rule.
