Two long
Two long, thin, parallel conductors are kept very close to each other, without touching. One carries a current i, and the other has charge λ per unit length. An electron moving parallel to the conductors is undeflected. Let c = velocity of light.

Two long, parallel conductors carry currents in the same direction as shown in Fig. Conductor A carries a current of 150A and is held firmly in position. Condcutor B carries current IB and is allowed to slide freely up and down (parallel to A) between a set of non-coducting guides. If the mass per unit length of conductor B is 0.001gcm−1 , what value of current IB will result in equilibrium when the distance between the two conductors in 2.50 cm?

Two long, straight wires, one above the other, are separated by a distance 2a and are parallel to the x-axis. Let the y-axis be in the plane of the wires in the direction form the lower wire to the upper wire. Each wire carries current I in the +x-direction. What are the magnitude and direction of the net magnetic field of the two wires at a point in the plane of wires: (a) midway between them? (b) at a distance a above the upper wire? (c) at a distance a below the lower wire?
