I'm pretty sure the compass bounces around, the larger concern would be whether the
deviation becomes perminant [damages the magnets in the compass] due to a large pulsing
magnetic field being applied under the a/c.  

 Having EMALS in a civilian settings is only part of the equation. The would also need a similar
[opposite] system to get the plane down and stopped on that same runway  :)
