In the figure, a long, straight copper wire (diameter 2.56 mm and resistance 0.944 Ω per 270 m) carries a uniform current of 24.0 A in the positive x direction. For point P on the wire's surface, calculate the magnitudes of (a) the electric field E→, (b) the magnetic field B→, and (c) the Poynting vector S→, and (d) determine the direction of S→ (a) Number Units (b) Number Units (c) Number Units (d)
