Aflashlight can be made that is powered by the induced current from a magnet moving through a coil of wire. the coil and magnet are inside a plastic tube that can be shaken causing the magnet to move back and forth through the coil. assume the magnet has a maximum field strength of 0.05 t. make reasonable assumptions and specify the size of the coil and the number of turns necessary to light a standard 1-watt, 3-v flashlight bulb.
