Define Magnetic Field and Magnetic Lines of Force - QS Study

Magnetic field: Magnetic field is the space in which a magnetic pole experiences a force or it is the space around a magnet in which the influence of the magnet is felt.


Magnetic lines of force: A magnetic field is better studied by drawing as many number of magnetic lines of force as possible. A magnetic line of force is a line along which a free isolated north pole would travel when it is placed in the magnetic field.
