Penetration of rotating transverse electric and magnetic fields

Rotating transverse magnetic fields have been used since the 1960s to drive azimuthal current in an axial plasma column. The conditions for penetration and synchronous electron rotation have been previously examined for resistive plasmas extensively. However, penetration of transverse inductive electric fields, which could cause significant ion heating at the magnetic null of a field-reversed configuration plasma, has not yet been investigated. Here, we compare the penetration of the two types of fields using the kinetic particle-in-cell simulation code, LSP.
