A long, cylindrical rod of radius a carries a uniformly distributed free current I. The rod is made of a paramagnetic material, which has a relative magnetic permeability µr slightly greater than 1. The resistance per unit length of this wire is R. Figure 2 (a) For the regions inside and outside the rod, find the a. magnetic field strength H, b. magnetic flux density B, c. magnetization M. (b) Write down Poynting’s theorem in words, and also in equation form. (Derivation is not needed, but you should explain each of the symbols used.) (c) By integration of the Poynting vector, show that the power flow per unit length into the wire from the Poynting vector is equal to the ohmic power dissipated per unit length in the wire.

We have an infinitely long wire, again with linear charge density λ = 10 μC/m. We have a point charge, again with q = 75 μC. Point S is zS = 10 m away from the wire on the z-axis, point P is zP = 5 m away from the wire on the z-axis, and point T is yT = 5 m away from the wire on the y-axis. Remember that the electric field at a distance r away from a wire is E→wire = 2 kλrr^ Figure 2: Figure for Problems 3-5 3. Potential change with radial path 1 point What is the energy change from point S to point P ? 4. Potential change with angular path 1 point What is the change in energy from point P to point T along the quarter-circle path? 5. Potential change with square path 1 point What is the change in energy from point P to point T along the square path? (Next two questions) We have an infinitely long wire of linear charge density 1 nC/m. You throw a ball with charge Q = −8 C and mass m = 2 kg away from the wire with initial velocity vi = 12 m/s. The ball is initially 4 meters away from the wire. 6. Change in potential 1 point After some time the ball's velocity decreases to 6 m/s, half its initial speed. What is the magnitude of the change in potential, in volts, from the initial position to this position of the ball? 7. Maximum distance 2 points What is the maximum distance the ball gets from the wire?
