You have a self-charging battery in your flashlight. The battery
has is connected to a coil with 100 turns, each an area of 2 x 10
4 m². There is a bar magnet sliding through the coil, which can
change the field from 0 T to 0.08 T when it moves 4 cm into or
out of the coil. How fast do you need to shake the magnet to
make induce an EMF of 1.5 V and charge the battery?
