State the conclusions that can be drawn from Oersted's experiment.

Explanation

Conclusions that can be drawn from Oersted's experiment
(1) An electric current produces a magnetic fiela around it. The moving charge in the conducting wire is a source of magnetic field.
(2) The direction of the magnetic field produced by the current is the direction in which the north pole of the magnetic needle is deflected. Hence, from the experimental observations we can conclude that at any point near the current-carrying conductor, the magnetic field is perpendicular to (1) the length of the conductor and (ii) the line joining the conductor and the given point.
