Hand Crank Generator

How does a crank generator work? Using the kinetic energy. Well, I have the answer. The end of the handle that is inside the body of the device is covered with magnets. For this is a small dead air space and then a lot of shit coiled wires. By turning the crank, rotate the magnets create a magnetic field. The magnetic field induces an electric current in the coiled wires. If it is a flashlight handle, electricity is stored in a group of capacitors and / or batteries.

Moving a magnetic field through cables to induce a current flow. That's the basics. You can fill in the details.
