Propulsive Forces

• Static FxB force

  • Linear B: current carrying wire in B-field
  • Quadratic B: dipole-dipole interaction

• Dynamic Plasma forces (from a long list)

  • “Solar wind” sailing
    • Interaction size is determined by the “standoff distance” between the solar wind mag field & sail.
  • Tethers w/e- & w/ions
  • A “solar wind” ion engine
  • The MHD “solar wind” engine
