State Biot-Savart's law and express this law in the vector form.

Answer the following: (a) State Biot - Savart's law and express this law in the vector form. (b) Two identical circular coils, P and Q each of radius R , carrying currents 1A and sqrt(3)A respectively, are placed concentrically and perpendicular to each other lying in the XY and YZ planes. Find the magnitude and direction of the net magnetic field at the centre of the coils.
