Find magnetic field due to a long solenoid at a point inside the solenoid on its axis. Draw its magnetic lines of force and compare with electric lines of force of dipole. (b) A straight thick long wire of uniform cross section of radius a is carrying a steady current I. Use Ampere’s circuital law to obtain a relation showing variation of the magnetic field inside (r<a) and outside(r>a) the wire from the center of its cross section. Plot a graph showing the variation of the field B with distance r
