Question

what is Biot Savart law derive an expression for magnetic field at a point on the axis of a current carrying circular coil​

Answer 1

hey there !!!

answer:-

Moving Charges And Magnetism. Use Biot-Savart law to derive the expression for the magnetic field on the axis of a current carrying circular loop of radius R. Draw the magnetic field lines due to a circular wire carrying current I. is cancelled out and the x-component remains.

hope it helps
