Types
Ferromagnetism (save for later)
Paramagnetism ( para - from parallel to external B)
Diamagnetism (dia - opposes external B)

This is a torque that causes the m to align with external B field.
Paramagnetism
often in odd numbered electrons
Atomic orbits
not only do electrons spin inside the atom, but they also revolve around the nucleus.
point. - the change in m is opposite the external B field. diamagnetism
Magnetization
end story. objects get magnetized, either the spin of the electron or the orbit of the same.
Magnetization is akin to polarization
it is the magnetic dipole moment per unit volume.
Find the force between two magnetic dipoles m and m , a distance d apart.

"Can we go over the mathematical derivations for paramagnetism and diamagnetism?"
"what's a good way to conceptualize the difference between diamagnetism and paramagnetism? I got those two mixed up at first on the pre-quiz.."
"What exactly accounts for the differences between ferromagnetism, paramagnetism, and diamagnetics?
". Something about the Pauli exclusion distracted my reading. Can we go over that or brief explain it in class
