Solution
A magnetic field is a picture that we use as a tool to describe how the magnetic force is distributed in the space around and within something magnetic. The direction of the magnetic field lines at a place can be determined by using a compass needle. The north end of the needle of the compass indicates the direction of the magnetic field at the point where is placed.
