Solution

Step 1: Definition of 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.

Step 2: Diagram for representing magnetic lines of force.

Step 3: Origin of magnetic lines of force.

  1. Magnetic lines of force are thought to originate from a magnet's north pole.
  2. After that, go across space until you reach the South Pole. The lines then go from the South Pole to the North Pole inside the magnet, completing the loop.
  3. Magnetic force lines are closed curves. Their direction is from the north pole to the south pole outside the magnet, and from the south pole to the north pole inside the magnet.
  4. The lines of force can emerge from the north pole of the magnet perpendicular to the surface of the magnet and merge into the south pole again perpendicular to the surface of the magnet.
  5. The magnetic field lines do not intersect.

Magnetic lines of force always originate from the North Pole and end at the South Pole.
