Magnetic lines of force always originate from the North Pole and end at the South Pole.
Magnetic lines of force
Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet. These lines do not exist actually but are imaginary lines used to illustrate and describe the magnetic field pattern.
- the magnetic lines of force are assumed to originate from the north pole of a magnet
- Then pass through the surrounding space and then arrive at the South Pole. Then these lines travel inside the magnet from the South Pole to the North Pole and hence complete the loop.
- Magnetic lines of force are closed curves. Outside the magnet, their direction is from the north pole to the south pole, and inside the magnet, these are from the south to the north pole.
- The lines of force can emerge out of the magnet’s north pole at any angle, and these can merge into the South Pole at any angle.
- The direction of magnetic lines of force at any point gives the direction of the magnetic force on a north pole placed at that point.
