Where do magnetic lines of force originate relative to the magnet's poles?

• A. Originates at the North pole and terminates at the South pole.
• B. Originates at the South pole and terminates at the North pole.
• C. Originates at the center of the magnet.
• D. Originates at random locations on the surface.

Answer: (A)

Magnetic lines of force emerge from the magnet’s North pole and enter the South pole. Outside the magnet, they leave the North pole, spread through space, and curve into the South pole; inside the magnet, the lines continue from the South pole back to the North, completing a continuous loop. Thus, their external behavior is that they originate at the North pole and terminate at the South pole. They don’t originate at the center or at random surface points.
