1. Chapter 32 Maxwell’s equations; Magnetism in matter In this chapter we will discuss the following topics: -Gauss’ law for magnetism -The missing term from Ampere’s law added by Maxwell -The magnetic field of the earth -Orbital and spin magnetic moment of the electron -Diamagnetic materials -Paramagnetic materials -Ferromagnetic materials (32 – 1)

2. The magnetic flux through each of five faces of a die (singular of ''dice'') is given by Φ B = ±N Wb, where N (= 1 to 5) is the number of spots on the face. The flux is positive (outward) for N even and negative (inward) for N odd. What is the flux (in Wb) through the sixth face of the die? A.1B.2C.3D.4E.5
