The magnetic field B at the centre of the loop is 0
Explanation:
As the middle of the circle, i.e. point O, is on the same line of two long direct wires, because of each straight wire, the magnetic field at O is zero.
Because ABC and ADC wires are similar, At point A, the current is distributed equally in two sections. So, because of that ABC and ADC throughout O, the magnetic field is magnitude equal but is opposite in direction. (As indicated in the figure).
O (net magnetic field) = 0 (total magnetic field)
