Question
A current loop ABCD is fix on the plane of the paper as shown in the figure The arcs BC (radius = b) and DA (radius = a) of the loop are joined by two straight wires AB and CD A steady current I is flowing in the loop Angle made by AB and CD at the origin O is 30
Another straight thin wire with steady current I1 , flowing out of the plane of the paper is kept at the origin.
The magnitude of the magnetic field (B) due to loop ABCD at the origin (O) is
- zero
The correct answer is:
