A dynamo flashlight works by producing its own electricity. The flashlight has a crank that is turned by the operator. The crank runs a small generator inside that produces enough electric to run the flashlight.
The inside of a flashlight usually contains a light bulb or LED, a reflector to direct the light forward, and batteries to power the light source. There may also be a switch mechanism to turn the flashlight on and off.
The heating element found inside a flashlight bulb is typically made of tungsten, which has a high melting point and can withstand the heat generated in the bulb. Nechrom is not a common material used in flashlight bulbs.

A flashlight bulb typically contains a tungsten filament as the heating element. When electricity passes through the filament, it heats up and produces light through incandescence.
A shake flashlight works by using a magnet and a coil of wire to generate electricity through electromagnetic induction. When the flashlight is shaken, the magnet moves back and forth inside the coil, creating a changing magnetic field. This induces an electric current in the wire, which is then stored in a capacitor or rechargeable battery to power the flashlight's LED light.
It happens when you turn on the flashlight and a circuit is created through the batteries, through the light filament, back down the outside of the batteries to the end of the batteries, etc. Switching off the flashlight breaks the circuit, curtails the chemical reaction in the batteries, and the light goes out.
