Question 3: Inducing a Magnetic Field - Magic Magnets! You have a bar magnet with the south end of the magnet pointed towards a metal ring. Remembering back to your grade 12 physics class, you remember that moving a magnet near a metal coll will induce a current, an application of Lenz's Law. a) Will the initial direction of the induced current be clockwise or counterclockwise as the south side of the bar magnet passes through? Please explain your answer using both a picture and words. (Fun fact: the magnet will slow down as it falls through this loop, and speed back up once it has fully passed through!) [2T 2c] b) You decide to try the experiment again. This time, you use a ring that has a gap in the side. The magnet falls through without slowing down. Why doesn't it slow down? Please explain your answer using both a picture and words. [27 2C] Image for Q3a Image for Q3b N N S S Open Gap
