    Here is the scheme :

    The coil is NOT connected to the batteries ! and those are LR41 batteries cells and not rechargeable ones ! There is no rectifier ! And the coil is too little to feed the necessary voltage !
    So it is a simple battery flashlamp…

    I have one of these flashlights – the exact same item. I bought it at a swap meet where I ended up spending the night in a tent, and needed some quick portable light. Did you notice also that the “coil” is just for show, as is the “magnet.” The coil is only wrapped one layer deep – not enough to create any significant flux. Even if it did, as stated above, there is no circuit to use the current. The flashlight runs on three coin batteries. The “magnet” is just a slug of metal. It does not stick to anything. Caveat emptor.
