Suppose we have two infinitely long parallel wires separated by carrying identical currents, i. a third parallel wire of length /, mass m, and current i3 is being levitated above by the two infinitely long wires. (a) if we assume that the infinite wires have current flowing in the +z-direction (out of the page), which direction is the current in the third wire flowing? explain your reasoning. (b) provide an expression for the force of one of the infinitely long wires on the levi- tated wire. express your answer in terms of given variables (no numbers) and appropriate constants. assume that all wires are separated by the same distance a. (c) what must the current be in the infinite wires in order to accomplish the setup desc a distance of a and ed in part (b)? suppose a 2cm, 15m, m = 2g, and i3 =10a
