A square coil ABCD lies flat on a horizontal table with side AB oriented along the north–south direction. A uniform magnetic field of 0.2T is applied vertically upward through the coil.
a. (i) If a current of 2A flows from A to B, state the direction of the force on side AB.
b. (ii) State the direction of the force on the opposite side CD.
c. (iii) Will the coil tend to rotate? If yes, about which axis (north–south or east–west)?
