I remember (long ago) a high school physics test question if satellites are affected by the earth’s magnetic field. Since then, I Googled it can induce about 0.2 volt increase*. But, is there an uncomplicated answer to how this doesn’t play havoc with sensitive instruments and circuitry?
(If not the induced potential per se, then what about a small induced current?)
*I wager it may actually induce voltage ranging from -0.2 to +0.2 volts?
