## When a magnet is brought close to the loop, the induced current in the loop will be in a direction such that the part of the loop facing the magnet repels the magnet. Using the above statement, choose the correct answers. When the north pole of the magnet is brought close to the loop, the current will be anticlockwise When the south pole of the magnet is brought close to the loop, the current will be clockwise When the south pole of the magnet is brought close to the loop, the current will be anticlockwise When the north pole of the magnet is brought close to the loop, the current will be clockwise
