The illustration shows a magnetic field B is outward to the left of the wire and inward to the right of the wire. The wire carries a current I equals 10 amperes, flowing upward. The metal rod of length 30 centimeters is moving upward at a distance of 10 centimeters from the wire in the inward magnetic field with a velocity u. The end points of the rod are labeled terminal 1 and 2 where the terminal 1 is next to the wire. The radial distance from the wire is r.
