We study the electronic current of a two-dimensional electron system confin
ed to a thin strip and subject to a perpendicular, space homogeneous but ti
me oscillating magnetic field. The geometry of the field producing magnet i
s chosen so that the resulting space and time dependent induced electric fi
eld points along the direction of the bar. Within the framework of the semi
classical Boltzmann equation we derive analytical expressions for the elect
ric current density both in the longitudinal and transverse directions as a
function of the magnetic field strength B-0, its oscillation frequency Ome
ga, and the location of the bar center. It is found that the time dependenc
e of the current density is expressed in terms of solutions of a Mathieu di
fferential equation whose coefficients are functions of the time, B-0, Omeg
a, and the bar confining potential strength Omega (0). As functions of thes
e parameters, the solutions of the Mathieu equation are known to exhibit st
able or unstable behavior which in turn imply similar results for the curre
nts. Such distinct behavior yield interesting measurable physical effects.
The inclusion of diluted impurities and Coulomb interelectron interaction a
re considered in this context and are shown not to change these results qua
litatively.
