A group of magnetic force lines going from the north pole of a magnet to the south pole is called magnetic field line.
What Is Magnetic Force?
If we put a point charge q within the presence of both a magnitude field given by magnitude B(r) and an electric field given by a magnitude E(r), at that point the whole force on the electric charge q can be composed as the whole of the electric force and the magnetic force acting on the question .
This force is named as the Lorentz Drive. It is the combination of the electric and magnetic force on a point charge due to electromagnetic fields.
