[amsat-bb] Re: Could we raise orbit thru magnetorque?

Wise answer. Tks! David ! It will change assumption.

Idea is like having a magnet with its south pole pointing to earth when satellite is over earth north (which is a magnet south). It is supposed to be repelled. Instead of magnet a coil with controllable current will be used. 

Tks again !

    Argument is:  if when satellite is in the north, a north magnetic field is applied on z plane, will satellite raise orbit ? Same but opposite on south. Considering limited energy available could this raise be significant if applied on all orbits ?.

  Very interesting. Don't know the answer.

  However, if you are in the North then you need to generate a 'south pole' to repel the satellite.

  -Remember, the geographic north pole is a magnetic south pole-  That's why the north pole of your compass points towards it.
