Definition
Magnetic field lines are visual representations of the direction and strength of a magnetic field. They show how a compass needle would align at different points in space.
Analogy
Think of iron filings sprinkled around a bar magnet. The filings arrange themselves along curved paths, showing the shape and direction of the invisible magnetic field surrounding the magnet.
