In this activity, current is made to flow through a conductor (copper wire) and a magnetic compass is placed near it. The moment current begins to flow in the wire, the magnetic compass is deflected. How can the compass move when it is not touching the wire? This means that there is some relation between the current and the magnetic field of the compass. This introduces us to an entire new realm of physics called the Electromagnetism, in which the electricity and magnetism are linked.

this activity states that when current is passed throgh the wire there is a magnetic field which is produced by wire and we can say that as we also pit a compass needle near wore so when current os pass magnetic field produced because of that compass neddle deflected in other direction
