SECTION AYou must answer ALL questions in this Section.1. Explain (with specific reference to Maxwell's equations) why a traveling wave in theelectric field must always be associated with a propagating wave in the magnetic field.2. Explain why a free charge q will be attracted to the surface of an electrically neutralconductor, and explain how you expect this force to vary with distance compared tothe regular Coulomb force between two charges.3. Explain how you could estimate the refractive index of glass given a power supply,a sheet of glass, two flat pieces of metal, some wire and appropriate instruments formeasuring the properties of electrical circuits.4. With reference to one or more of Maxwell's equations, explain why it is apparentlyimpossible to find a static magnetic field which has a "porcupine" configuration - thatis, a surface at which all the field vectors are pointing in the outward direction.5. Describe the phenomenon of diamagnetism. A grape (which consists mainly of water,a diamagnetic material) is placed at the top of a very powerful solenoid where it issuspended in space. Sketch the magnetic field seen near the top of the solenoid and thelikely magnetic field of the grape. Explain why the grape will feel a repulsive force.
