Mart,
Many years ago, I brought this subject up on another forum in respect to AoA control. The idea was to ionize the air in front of an airfoil and then use magnetism to direct the air over or under the airfoil.
An unnamed professor at the University of Maryland (not Leishman) replied and said that only the impurities in the air could be magnetized.
I ate crow and gave up.
