Exam 32: Maxwells Equations; Magnetism of Matter

A positively charged ion, due to a cosmic ray, is headed through Earth's atmosphere toward the center of Earth.Due to Earth's magnetic field, the ion will be deflected:

The units of magnetization are:

If an electron has an orbital angular momentum with magnitude L the magnitude of the orbital contribution to its magnetic dipole moment is given by:

An electric field exists in the cylindrical region shown and is parallel to the cylinder axis.The magnitude of the field might vary with time according to any of the four graphs shown.Rank the four variations according to the magnitudes of the magnetic field induced at the edge of the region, least to greatest.

The spin magnetic dipole moment of an electron:

A cylindrical region contains a uniform electric field that is parallel to the axis and is changing with time.If r is the distance from the cylinder axis the magnitude of the magnetic field outside the region is:

The molecular theory of magnetism can explain each of the following EXCEPT:
