Question

A single turn circular loop is formed from a very long wire in three different ways as shown in the figures. The radius of the circular loop is R = 33.9 cm and the wire carries the same electric current I = 14.4 A in all three cases. In the first and in the second case the plane of the circle is parallel to the straight wire segments, in the third case the plane of the circle is perpendicular to the straight segments. The straight segments are very long in all three cases in both directions.

I got the the first two cases correct but I can't seem to get the third case. The answer im coming up with is 3.92E-10 T

Explanation / Answer

what is to be found out??? and if it is magnetic field that is to be foun dout then the magnetic flux due to the long wire at the centre of the third loop is zero. because the loop is perpendicular and there is no flux passing through the loop in ths case.
