I was just wondering;
What would happen if a Halbach array of magnets were placed just beneath the heat shield on a reentry vehicle? The plasma produced by reentry is, essentially, charged particles moving at high speed. Would a Halbach array magnetically levitate the reentry vehicle away the from the plasma (IOW, recall the plasma away from the heat shield) the way it does with an inductrack maglev?
If so, would the increase in distance result in less heat being transferred to the vehicle, or with the work being done on the magnets caused them to heat up?
