Verify the Ampere's law for magnetic field of a point dipole moment `vecM=Mhatk`. Take C as the closed curve running clockwise along (i) z-axis from `z=agt0` to `z=R`, (ii) along the quarter circle of radius R and centre at the origin, in the first quadrant of x-z plane, (iii) along the x-axis from `x=R` to `x=a`, and (iv) along the quarter circle of radius a and centre at the origin in the first quadrant of x-y plane.
