Write the experimental procedure carried ouyt by Faraday, that relative motion between a bar magnet and a wiore loop produce current.

Using Biot-Savart Law find the magnetic field intesity due to current carrying loop at an external point on the axis that passes perpendiculary to the plane of the loop through the centre. What is the field intensity at the centre?

A rectangular coil carrying current is placed in a uniform magnetic field in such a way that normal to the coil makes an angle theta with the direction of magnetic flux density. Find the magnitude of torque acting on the coil Define magnetic moment of a current loop.

A charged capacitor is connected to an inductor at an instant of time t=0.If the capacitor and the inductor are taken to be pure, write down the equation of effective potential difference across the combination at any instant of time t and solve it for instantaneous current through I the combination.Explain brefly the exchange of electric and magnetic energy between the capacitor and the inductor.

Write the Oersted's investigation on deflection of a magnetic compass needle when placed nearby a long straight current carrying conductor.
