As shown in the figure two infinitely long, identical wires are bent by `90^(@)` and placed in such a way that the segments LP and QM are along the x-axis , while segments PS and QN are parallel to the Y-axis If OP=OQ=4 cm ,and the magnitude of the magnetic field at O is `10^(-4)` T, and the magnitude of the current in each wire and the direction of the magnetic field at O will be `(mu _(o) =4pi xx10-7NA^(-2)):`
