Ultrasound is sound not magnetic. Sound waves are mechanical vibrations (compressions and rarefactions of the media--such as air, flesh, water--it is transmitted through). I believe that is an entirely different series of studies.

The ultrasound vibrations are generated by an electric motor, which has an associated magnetic field -- I don't know the field strength, though.
