A magnetic field is the region around a magnet or a current-carrying conductor where magnetic force can be felt.

When a question asks about magnetic influence, mention both the source and the region around it where force acts.

Field lines are imaginary lines used to show the shape, direction, and strength of a magnetic field.

If asked to draw field lines, keep the curves smooth, closed around the magnet, and never let two lines cross.
