Hi All
I want to know how
A Fixed magnet (which
casues its own static magnetic field) will affect
any other Electromagnetic (radio) signal especially
when we are trying to carry energy/information using
magnetic component of EM wave which is typical for
near field applictions.
Best Regards

As long as we are concerned only by the antennas,
I don't think a DC field will have any impact. Antenna
are resonnant circuit, and so are also the receiving
networks, a DC field will be mostly rejected.
Would the situation you describe be a problem
we would have a serious issue with the earth magnetic
field.
