  A charged particle moving through a plasma experiences a friction force that
commonly acts antiparallel to its velocity. It was recently predicted that in
strongly magnetized plasmas, in which the plasma particle gyro-frequency
exceeds the plasma frequency, the friction also includes a transverse component
that is perpendicular to both the velocity and Lorentz force. Here, this
prediction is confirmed using molecular dynamics simulations, and it is shown
that the relative magnitude of the transverse component increases with plasma
coupling strength. This result influences single particle motion and
macroscopic transport in strongly magnetized plasmas found in a broad range of
applications.
