Here's a quote from "Fields and Waves ...", by Ramo and Whinnery:

"A perfect conductor is usually understood to be a material in which
there is no electric field at any frequency. Maxwell's equations
ensure that there is then also no time-varying magnetic field in the
perfect conductor."

Depends on what your definition of "is" is.

Sorry, I meant "in".
