Magnetic Field And Field Lines

Around a bar magnet, magnetic field lines emerge from the north pole, curve around the magnet, and enter the south pole. Inside the magnet, the lines continue from the south pole to the north pole, forming closed loops.

You can visualize magnetic field lines by sprinkling iron filings around a magnet or by using a small compass. The iron filings align themselves along the magnetic field lines, forming a pattern that reveals the field's shape and direction.

Magnetic field lines are imaginary lines used to represent the strength and direction of a magnetic field. They help us visualize how the magnetic force behaves around a magnet or a current-carrying conductor.
