Answer: A line of Force is a straight or curved route, and the tangent at each point indicates the electric field intensity at that place. Michael Faraday invented electric force lines in 1837. When a unit or point charge enters another charged particle’s electric field, a force is created. Electric lines of force indicate the force’s direction. Electric field lines are force lines.
Properties
Magnetic lines arise from the north pole and converge in the south. Magnetic line density reduces as pole distance rises. Field lines within the magnet go from South to North. Magnetic lines never cross. The magnetic field’s strength is related to how near the force lines are.
