Principle and Working:
A current carrying coil produces a magnetic field along its axis which is defined by Biot Savart’s law.
In the present setup, the study of magnetic field along the axis is investigated with coils having different dimensions and turns. The magnetic field is measured using a axial hall probe and digital gaussmeter.
