Figure shows a long wire bent at the middle to form a right angle. Show that the magnitudes of the magnetic fields at the points
Q and
R are unequal and find these magnitudes. The wire
w1 and the circumference circle are coplanar and
w2 is perpendicular to plane of paper. Also find the ratio of field at
Q and
R.
