The flux lines around a magnet leave the north pole and enter the south pole. Which statement correctly describes the direction of the flux lines?

The flux lines around a magnet leave the north pole and enter the south pole. Which statement correctly describes the direction of the flux lines?

• A. They leave the north pole and enter the south pole
• B. They leave the south pole and enter the north pole
• C. They do not exist
• D. They radiate outward from all directions

Answer: (A)

Magnetic field lines show the direction of the magnetic influence around a magnet. In the region outside the magnet, they travel from the north pole to the south pole, forming closed loops by returning from south to north inside the magnet. This convention means flux lines emerge from the north and terminate at the south, so the description that they leave the north pole and enter the south pole is the correct one. They don’t originate from the south outward, nor do they radiate in all directions; their external path is governed by the magnet’s poles and they complete the loop inside the material.
