Which pole is associated with the starting point of magnetic lines of force outside a magnet?

Which pole is associated with the starting point of magnetic lines of force outside a magnet?

• A. North pole.
• B. South pole.
• C. Both poles equally.
• D. There is no starting pole.

Answer: (A)

Magnetic field lines are drawn to show direction, and outside a magnet they emanate from the north pole and curve around to enter the south pole. This convention makes the north pole the starting point of lines when you look at the field outside the magnet. Inside the magnet, the lines return from south to north, completing a continuous loop. So the starting point of the lines outside is the north pole, while the south pole is where they terminate. There isn’t a notion of a starting point elsewhere or of no starting point in the external field.
