eli5 Why Earth magnetic field doesnot affect electric appliances especially at poles where field is greatest

In: 1

Answer 1

its weak and its static.

magnetic fields mostly affect electronics only when changing, which the earth’s field mostly doesnt.

and even when changing, its weak (on human/electronics scales) to begin with, so it cant do much either way.
