(a) If your metal car moves over a wide, closed loop of wire embedded in a road surface, is the magnetic field of the Earth within the loop altered? Does this produce a current pulse?

(b) Compare and contrast Biot-Savart Law in magneto-statics with Coulomb's Law in electrostatics.

(c) The electrons in the beam of television tube have an energy of 12keV (1eV = 1.6 x 10-19 J). The tube is oriented so that electrons move horizontally from south to north. At the current location, the Earth's magnetic field points roughly vertically down and has magnitude B= 6 x 10-5 T.

i. In what direction will the beam deflect?

ii. What is the acceleration of a given electron associated with this deflection?

(d) In Faraday's experiments, what would be the advantage of using coils with many turns? Use Lenz's law to determine the direction of induced current in each case.
