  The coherent and Fock states of a charge moving in varying homogeneous
magnetic field are studied in the tomographic probability representation of
quantum mechanics. The states are expressed in terms of quantum tomograms. The
coherent states tomograms are shown to be described by normal distributions
with varying dispersions and means. The Fock state tomograms are given in the
form of probability distributions described by multivariable Hermite
polynomials with time-dependent arguments.
