In this problem, you will design a shake flashlight that can power a standard 1W, 3V flashlight bulb. In a shake flashlight, a coil of wire 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. Making additional reasonable assumptions as needed, specify the dimensions and number of turns of the coil of wire in your flashlight

The number of turns in the coil can be determine from induced emf.
…
…
Here, is the number of turns, is the induced emf, is the change in electric flux, and is the change in time.
