Introduction to Magnetic Fields 8.1 Introduction We have seen that a charged object produces an electric field E G at all points in space. In a similar manner, a bar magnet is a source of a magnetic field B G. This can be readily demonstrated by moving a compass near the magnet. The compass needle will line up
