explain the direction sir
Dear student,
so (i) 4.5 x 10-7 T outside the plane of paper,
(II), the semicircle is bent in opposite direction, so the magnitude of magnetic field will be same (similar process as described in part i) i.e. 4.5 x 10-7 T
but here the current will flow in clockwise direction
i.e. loop behaves as south pole
so magnetic filed lines will directed towards it.
so the magnetic field in part (ii) 4.5 x 10-7 T into the plane of paper.
Regards,
