1. A loop of wire passes through a constant magnetic field going out of the page. As the loop begins to enter the magnetic field what direction will the current be induced? Counter clockwise Into the page Out of the page In a zig zag around the earth Clockwise 2. Faraday’s low of induction states that the emf induced in a loop of wire is proportional to (magnetic flux)/(time) (time)/(magnetic flux) (magnetic flux)(magnetic field) (current)/(time) (magnetic flux)(area) 3. The number...
