The Motion of Solar Wind Charged Particle in a Sinusoidal Vibrating Magnetic Field
Abstract: The motion of solar
wind charged particle in a small perturbed magnetic field lines of magnitude B1
is derived through a perturbed Lorentz force. By introducing a small sinusoidal
velocity perturbation v1 in transverse
direction to the original velocity field vo, a small perturbed magnetic field
is resulted from the original magnetic field of magnitude B0. A system of
simultaneous differential equations describing the perturbed Lorentz force in
Cartesian coordinates is obtained. These equations, denoted as RESY, are then
treated numerically to follow qualitatively the behaviour of the charge motion
locally. The squared space velocity resulted from RESY are twice to three times
larger than the initial velocity squared in the case of constant magnetic
field. Here the initial velocity was normalized to unity,whereas its value may
be estimated from the well-known Parker exponentially increased solar-wind
velocity. Vibrating magnetic fields might be one candidate to explain the
observed very high velocities for some solar wind particles.
