A magnet in the form of a cube is placed on a piece of cork that floats on water. The cube is marked with four faces W, X, Y and Z and the compass needle points in the direction as shown in the figure. The arrow beside the N symbol represents the direction of the geographical north pole.
Which of the following faces denote the N - pole and S - pole of the magnet?
N - pole (Y)
S - pole (Z)
A compass has a magnetic needle that works as a pointer to geographical north of the Earth. This is because the north pole of the magnetic needle gets attracted to the magnetic south pole of the Earth (which is also its geographical north pole). Thus, we can say that in the given case, Y denotes north pole. Similarly, Z denotes the south pole of the magnet.
