It was.
But, that was before icons happened.

Long ago (about 1978 I think), I used to use a terminal ("the computer" was
400 miles away) in an alcove (excavating for a mine ?).

On irregular occasions some minutes apart the screen image would sway to
and fro left to right with a "wave" that ran up the screen. All still
perfectly legible

We discovered it was caused by the loop of traction cables for the
passenger lift on the other side of the alcove wall. These hang in a "tail
below the lift and passed a few feet away from the terminal.

Knowing the magnitude of the fields involved and whether they met any
then-existing or current standards, and whether it actually matters, would
be interesting. Bzzzt ...
