Properties of magnetic lines of force

Michael Faraday introduced magnetic lines of force to explain how magnets attract or repel objects. These lines have certain important properties:

1. Imaginary Lines: The lines of force are not real; they are a way to visualise how magnetic forces act.
2. Direction of Flow: They always flow from the north pole to the south pole of a magnet, whether it is the same magnet or a different one.
3. Tension-like State: These lines act as if they are stretched springs, pulling opposite poles together.
4. Repulsion: Magnetic lines of force repel each other, explaining the repulsion between like poles (north-north or south-south).
5. No Intersection: The lines of force never cross each other.
6. Field Strength: The number of lines at a specific point determines the strength of the magnetic field in that area. More lines indicate a stronger magnetic field.

These properties explain how magnets behave: Opposite poles attract because the lines between them pull like stretched springs. Like poles repel due to the repulsive nature of the magnetic lines.
