Sailboats typically use metal vertically-oriented masts (the long support that holds up the sails. Given a 10m long mast and a boat speed of 4.0m/s, and earth’s surface B-field of roughly 1.0 gauss, how much voltage difference can we expect across the mast when sailing eastward? What part is most positive/negative on the mast?
