A horizontal metal bar oriented east-west, is dropped straight down at a place where Earth's magnetic field is due north. As a result, an induced emf develops between the two ends of the bar. What would be the direction of the induced potential difference ?

No answer text provided.
East to west, the west end being at higher potential (accumulating positive charges).
Neither end carries any excess charge
East to west, the east end being at higher potential accumulating more positive charges.
West to east, the west end being at higher potential accumulating more positive charges
