A bar magnet is pulled through a conducting loop along its axis with its south pole entering the loop first. Draw the graphs of the induced current |
Answer» Solution :When the south pole of the magnet moves TOWARDS the conducting loop along its axis, then according to Lenz's LAW, the induced current will be clockwise when viewed along the motion of the magnet. According to the given question, induced current is positive in this CASE. Again, when the magnet goes to the other SIDE ACROSS the loop, the direction of the induced current will be anticlockwise. In this case, induced current is negative. Variation of induced current with time is shown in.
