The Hall voltage across a piece of semiconductor is 5 V, the charge density of the semiconductor is 2x10" electrons per square m, the thickness of the semiconductor is 0.5 mm, and the current used to find the Hall voltage is 1 micro amp. a. What is the magnetic field? b. What happens if we keep everything else in the measurement setup the same and double the magnetic field? c. What if we doubled the current used for the measurement?

A section of superconducting wire carries a current of 100 A and requires 1.00 L of liquid nitrogen per hour to keep it below its critical temperature. For it to be economically advantageous to use a superconducting wire, the cost at cooling the wire must be less than the cost of energy lost to heat in the wire. Assume that the cost of liquid nitrogen is $0.30 per liter, and that electric energy costs What is the resistance of a normal wire that costs as much in wasted electric energy as the cost of liquid nitrogen for the superconductor?
If you pick up and shake a piece of metal that has electrons in it free to move as a current, no electrons fall out. Yet if you heat the metal, electrons can be boiled off. Explain both of these facts as they relate to the amount and distribution of energy involved with shaking the object as compared with heating it.
