is there an easy way to measure the weber stength of a magnet? Answered
Have been given the task of creating a circuit powered by a rotating
magnet in a copper coil that will charge a capacitor long enough to
light an LED for 600 seconds after the rotating magnet has stopped.
In all the magnet charge up torches I've opened, there are two 3V Lithium Cells (CR 2032) between the generator and the circuit. These cells aren't rechargable. The current from the generator is AC.
I know this shouldn't be too difficult, but can't figure out how to approach it with so many unknown variables. Just looking for any help possible for value of capacitor or resistor.
Thanks for any help!
