                          Chapter: MAGNETIC EFFECT OF ELECTRIC CURRENT





               LESSON NOTES:

               Introduction

                     We already learned about heating effects of electric current in previous chapter
                       about electricity. Now in this chapter we shall study about another phenomenon
                       related to current that is magnetic effects of current.
                     Hans Christian Oersted (1777-1851) experiments showed that electricity and
                       magnetism are related to each other.

                   















               An electric current carrying wire behaves like a magnet:-
               Let us now describe an experiment that shows the presence of magnetic field near a
               current carrying wire.
               ACTIVITY showing presence of magnetic field near current carrying wire:-


                     This experiment is also called Oersted Experiment.
