2. Since a current-carrying wire is acted on by a magnetic force, it would seem possible to suspend such a wire at rest above the ground using the Earth's own magnetic field. In what direction would the current have to be in a long, straight wire located at the equator to perform such a feat? 1) Up 2) Down 3) East 4) West
