Consider, you have a magnet and a loop of conducting wire as shown in the figure. If you move the magnet close to the loop, it will induce electric current. What would be the direction of magnetic field and its movement to induce current (Clockwise) in the loop? Is there any alternative way to generate that clockwise induced current?
