Chapter 32 Maxwell’s Equations # “Magnetism of Matter” skipped

32.2: Gauss’ Law for Magnetic Fields: The law asserts that the net magnetic flux  B through any closed Gaussian surface is zero. Here B is the magnetic field.

32.3: Induced Magnetic Fields: Here B is the magnetic field induced along a closed loop by the changing electric flux  E in the region encircled by that loop.

32.3: Induced Magnetic Fields: Ampere Maxwell Law: Here i enc is the current encircled by the closed loop. In a more complete form, : the displacement current : the displacement current density

Example, Magnetic Field Induced by Changing Electric Field:

Example, Magnetic Field Induced by Changing Electric Field, cont.:
