Magnetic Field Lines
Magnetic field lines are imaginary lines used to represent the strength and direction of a magnetic field around magnets or electric currents. They indicate how the magnetic force would act on a hypothetical test magnet placed in the field. The lines emerge from the north pole of a magnet and enter the south pole, showing the field's flow. The density of these lines indicates the field's strength; closer lines mean a stronger field. Overall, magnetic field lines help visualize and understand how magnetic forces operate in various situations, such as in wires carrying electricity or around permanent magnets.

Magnetic field lines are visual representations of a magnetic field's strength and direction. They are imaginary lines that show how the magnetic force acts in space around a magnet. The lines emerge from the magnet's north pole and curve around to return to the south pole. The closer the lines are together, the stronger the magnetic field in that area. These lines help us understand magnetic interactions and are useful in various applications, such as electrical engineering and physics, helping to visualize how magnets influence each other and nearby objects.
