Magnetism: Dilute Monatomic Gas: Applied Magnetic Field

APPH12-QKKZ2E

A dilute gas of monatomic hydrogen atoms at room temperature is a system of unpaired single-electron spins that do not interact with each other.

An applied magnetic field can easily align the magnetic moments of these atoms. However, when the applied magnetic field is removed the thermal motion of the atoms causes the magnetic moments to assume a random alignment.

The behavior of this monatomic hydrogen gas demonstrates which type of magnetism?

A

Ferromagnetism

B

Paramagnetism

C

Diamagnetism

D

Geomagnetism
