2. a. as you push a conductive loop into a magnetic field, energy is produced (as current flows through a resistor). where does this energy come from? b. a sheet of aluminum, with its normal oriented due west, falls vertically toward the earth’s surface. as it falls, it encounters a uniform magnetic field that is directed due west. (i) viewed from the east (i. e. looking west), what direction do the eddy currents flow in the sheet as it enters the field? (ii) viewed from the east (i. e. looking west), what direction do the eddy currents flow in the sheet as it leaves the field? (iii)the current dissipates electrical energy. in what form is that energy before the sheet has entered the field? (iv) in what form is that energy after the current has ceased to flow?
