The figure shows a coil made of a wire wrapped around a cylindrical object. The coil is connected to the battery and a current flows in the wire. The current flows out of the + terminal and into the - terminal of the battery, making the coil an electromagnet. One end of the coil becomes a north pole and the other becomes a south pole. Use a right-hand rule to figure out which poles are on which sides of the coil.
a)The north pole is on the left and the south pole is on the right.
b)The north pole is on the right and the south pole is on the left.
