How Does High-Frequency Ultrasound Affect Electromagnetic Fields?

[RedPhase]

What impact will a extremely high frequency of ultrasound have on a electromagnet?
Will the magnetic field also oscillate at that frequency?

What about a conductive wire transmitting electrical current? Will ultrasound on the wire cause the magnetic field to oscillate?

The ultrasonic wave is just a mechanical effect, so it won't affect a magnetic field directly.

But if the wire moves, it takes its magnetic field with it, so the magnetic field may move closer or further away from a given point, so it might change the observed magnetic field at that point.

By "ultrasound" do you mean Actual Sound or a high frequency AC Electric Current?
Sound will have no direct effect but high frequency (any frequency of) AC produces an oscillating field.* The problem will be that an electromagnet will have a high Self Inductance and that will limit the actual value of the current, which will severely limit the value of Magnetic field obtainable - unless you can tune out the inductance with an appropriate Capacitor. This is an added complication.
*The basis of a radio transmitting antenna.

Yes.

Ultrasound in the 1GHz+ range(not RF) that vibrates the magnetic field of a transformer core.

are you really really sure ??

I haven't heard of ultrasound at anything over ~ 100kHz let alone 1MHz 100MHz or higher

what is supposed to be generating this ultrasound?
