- A metal loop sits in the x-y plane. A magnetic eld is directed radians o the z-axis, and variesin time according to B(t) = Boe-at at where Bo and a are constants. Find the emf generated around theloop as a function of time.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 ? O Neither end carries any excess charge O West to east, the west end being at higher potential accumulating more positive charges O East to west, the west end being at higher potential (accumulating positive charges). O East to west, the east end being at higher potential accumulating more positive charges.
