When current is passed through a long, straight current-carrying wire a magnetic field is developed where magnetic field lines are in form of concentric circles around the wire in the center with their plane perpendicular to the straight wire. We can obtain these magnetic lines of force by sprinkling some iron fillings in a cardboard with a straight long wire passing through the center of the cardboard. This arrangement is connected to battery, key, rheostat, and ammeter. When current will pass through this iron fillings will get arranged in form of concentric circles around the wire.
