A wire is bent into the shape shown in fig and the magnetic field is measured at P_1 when the current in the wire is I. The same wire is then formed into the shape shown in the Fig and the magnetic field is measured at point P_2 when the current is again I. If the total length of wire is the same in each case, what is the ratio of B_1//B_2 ?
There are two straight conductors, carrying currents i_(1)" and " i_(2) . Both the conductors are kept parallel to each other at a separation 2d. The magnetic field is measured at a point midway between the conductors. Magnetic field intensity at the above specified point is 20 mu T when both the wiree carry current in the same direction but it becomes 80 mu T when the current in one of them is reversed. Assume i_(1) gt i_(2) and find i_(1)//i_(2) .
