Query: A charged particle in a magnetic field - Jarzynski Equality   We describe some solvable models which illustrate the Jarzynski theorem and
related fluctuation theorems. We consider a charged particle in the presence of
magnetic field in a two dimensional harmonic well. In the first case the centre
of the harmonic potential is translated with a uniform velocity, while in the
other case the particle is subjected to an ac force. We show that Jarzynski
identity complements Bohr-van Leeuwen theorem on the absence of diamagnetism in
equilibrium classical system.
