Question

write expression for the magnetic field at a point on the axial line of a current carrying circular loop. at what point will the magnetic field be maximum? plot this magnetic field vs distance from centre of the loop?

Answer 1

Answer:

Using Biot-Savart's law, derive an expression for magnetic field at any point on axial line of a current carrying circular loop. Hence, find magnitude of magnetic field intensity at the centre of circular coil. And direction of →dB is ⊥ to the plane containing I→dl and →r. Resolving →dB alonhg the x-axis and y-axis.
