Microwave propulsion

  1. Mar 5, 2004 #1
    I once asked a JPL engineer if radio energy could affect a magnetic field, his answer was just plain no. But I have a problem with microwave RF affecting bipolar molecules. I mean microwaves cause these molecules to vibrate and they do so because the RF affects the electric and magnetic fields of the atoms. So why can't RF be used to push something that has a magnetic field, similar to the vibration effect of microwaves?

    RF fields have an E and a H field
    the E field is electric, the H field is magnetic.
    They are both weak, but they do exist, and they interact with things (like your radio's antenna)
