Explanation:
A Magnetic field induction due to vertical loop at the It acts in horizontal direction magnetic field induction due to horizontal loop at the center is It acts in vertically upward direction as B1 and B2 are perpendicular to each other. Therefore the resultant magnetic field induction of the center O
