6-A square conducting loop is free to rotate about an axis that (1) runs through the midpoint of two sides of the loop (2) runs parallel to the other two sides of the loop. Now imagine that a big magnet is placed in the region where the loop is located, generating a large and uniform magnetic field... Which of the following choices below represents the torque on a loop whose two sides parallel to the axis of rotation are half the length of the original loop above?       The torque would be halved     The torque would be doubled     The torque would be quadrupled     The torque would be unchanged

Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.
