Question

Question Two parallel flat wires carry a current density in opposite directions, perpen dicular to the x-z plane (see Figure) 1. For a constant current density calculate the magnitude and direction of the magnetic field as a function of height, everywhere in space. You ignore boundary effects, and treat the wires as if they are infinitely large can 2. Draw a figure of the magnetic field strength vs. height in part I) calculated as 3. The current density is increased, linearly with time: J(t) J + at. Calculate the magnitude and direction of the electric field near the bottom of the top wire 4. What complicates the situation if the current density changes nonlin early, say J Jo Bt2? (explain qualitatively what changes, without solving the equations)
