Think 'Electro-Magnetic Link',
Electricity and Magnetism are forever linked in EVERYTHING we do as humans.
There is static electricity, but that does you no good, every thing you do will be magnets and conductors (Wiring)
So you don't have to worry with anything else.
The basis of ALL HUMAN CONTROLLED ELECTRONIC DEVICES YOU WILL MESS WITH WILL BE MAGNETS AND CONDUCTORS.

Rule 1.
A MOVING magnetic field will create or 'Induce' (Induction) an electric current in any conductor (Wire) it passes through.
LINK: http://en.wikipedia.org/wiki/Electromagnetic_induction
If you make a coil of wire, put a volt meter on that coil, pass a magnet through that coil,
You will be INDUCING an electric current.
If you move the coil of wire through a magnetic field, the coil will produce an electric current,
Since the magnetic field is MOVING relative to the coil (Conductor).

You can do it either way,
Move the magnet, or move the coil, doesn't matter since the magnetic field is still MOVING relative to the conductor.
ANY electrical Production you make will be based on the electromagnetic link and INDUCTION,
(To INDUCE a current in a conductor)
---------------------------------------------------------------------------------------
Rule 2.
Stationary magnetic fields DO NOT induce current.
A magnetic field SITTING STATIC in a coil of wire WILL NOT create, or Induce, a current.
The field MUST be moving relative to the conductor.
A prime example of this is a 'Stator' in a proximity sensor.
Proximity sensors are simply a magnetic core with wire wrapped around them.
When something Ferrous (Ferrous metals, means metals that are magnetic) comes close enough to the proximity sensor, the magnetic field of the magnetic core is attracted to the ferrous component, and the magnetic field reaches out to the component...
That means the magnetic field MOVES through the coil of wire around the magnetic core at it reaches out...
Moving magnetic field through a conductor means CURRENT is produced in the stator winding,
And the proximity sensor produces a signal that something has approached it.
Again, it's basic 'Rule 1' stuff, and since the proximity sensor has no moving parts, it lives a LONG time.
-----------------------------------------------------------------------------------
Rule 3.
When a current moves though a conductor, it creates a magnetic field.
This is also the other half of the electro-magnetic link.
When you wrap a coil of wire around a metal core (to focus that magnetic field) and run a current through that wire, it will create 'Electro-Magnet'.
A high voltage wire next to a low voltage sensor wire will create a magnetic field that will often trigger the sensor (False Trigger).
You can create an electro-magnet and use that electro-magnet to create even higher voltages in field windings. That's how an alternator and wound generator works.
Rule 4.
Generators use OUTSIDE force to create energy or current flow.
A hand crank generator or small wind mills usually use fixed permanent magnets and a spinning electrical winding inside,
Or they use fixed stator windings and a spinning permanent magnet.
While most engine driven generators use an electro magnet instead of fixed magnets.
