Moving Charges and Magnetism

It was hard to believe for a very long time that there existed a relationship between electricity and magnetism!┬áHans Christian Oersted’s observation made a discovery demonstrating a close relationship between the two. Oersted observed a pivoted magnet was deflected when kept in the neighbourhood of a wire carrying electric current.

The work of Oersted thus demonstrated that magnetic effects could be produced by moving electrical charges.┬áThe branch of physics which deals with magnetism due to the electric current is called electromagnetism. Let’s find out more in the following sections.
