Question
The three diagrams in the following figure show the lines of force (field lines) between the poles of two magnets. Identify the poles A, B, C, D, E and F.
Solution
1st diagram: Magnetic field lines are beginning from A and B. The lines are repulsive also. So, A and B are north poles.
2nd diagram: Magnetic field lines are ending on C and D. The lines are repulsive also. So, C and D are south poles.
3rd diagram: Magnetic field lines are beginning from E and ending on F. So, E and F are north and south poles, respectively
