An arrangement of three parallel straight wires placed perpendicular to plate of paper carrying same currents i along the same direction is shown in figure. Magnitude of force per unit length on the middle wire B is given by

Two long parallel wires separated by 0.1 m carry currents of 1A and 2A respectively in opposite directions. A third current-carrying wire parallel to both of them is placed in the same plane such that it feels no net magnetic force. It is placed at a distance of

Two long and parallel straight wires A and B carrying currents of 8.0 A and 5.0 A in the same direction are separated by a distance of 4.0 cm. Estimate the force on a 10 cm section of wire A

A uniform magnetic field of 1.5 T exists in a cylindrical region of radius 10.0 cm, its direction parallel to the axis along east to west. A wire carrying current of 7.0 A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire. If, the wire intersects the axis .

Two long parallel wires are at a distance of 4 cm. They carry currents I and 3I in same direction. Where will the field produced by both wires be zero from current I?
