This electromagnetism principle may be assisted by a make and break circuit and some proximity sensors at the top and bottom dead centres of the piston.

Someone has used a gasifier and captive-piston engine to make a one-moving part alternating-current generator. The piston is magnetized and the coils are in the body of the cylinder. The trapped air in the cylinder at each end of the piston acts as an air shock to eliminate rebound and impact damage. No sensors needed. No make and break circuit. The voltage drops to zero at the end-points of travel of the piston. Search on this and you can probably find the same one I saw. I think this is where they got the idea for those new shake-up LED flashlights.

look on the top of the controler, near the wire or sensor.

Metal objects such as the spoon & the pointed ends of the fork act to concentrate the electric field formed at the tips. This has the effect of exceeding the dielectric breakdown gradient of air, about 3 megavolts per meter (3×106V/m), causing sparks to form. This effect is somewhat analogous to the effect of St. Elmo's fire.\nMetal or conductive object placed into the microwave will act as an antenna, and its electrons will thus be thrashed back and forth through the object (a high frequency alternating current) causing some ohmic heating to occur\n\n- no damage to magnetron, but !

The PD will decrease as the current passing through it will drop due to current division

You may be able to design a device with little or no electrical knowledge or experience that is relatively safe for perhaps 99% of the population, depending on dumb luck and how you apply it, only to discover you are the unfortunate 1%.  Your entire idea is well ... shocking!

WHEN YOU PLACE YOUR HAND ON A CONDUCTOR AND YOU PLACE YOUR THUMB IN THE DIRECTION OF CURRENT FLOW, YOUR FINGERS WILL WILL POINT TO THE DIRECTION OF THE MAGNETIC FIELD AROUND IT.

Yes, thanks to the scanning tunneling electron microscope.

It is a very interesting idea.  If you are good at electronics, I may be able use the motors from a RC car.

well for my physics project for the boards i made a photoelectronic burglar alarm- at the heart of this was an LDR( Light Dependent Resistor) when the beam of light is obstructed (think laser in the movies-lol) the LDR resistance rises and the circuit inside is set into oscillation and the alarm sounds- other good projects would be a rain alarm, a rectifier, an electroscope,..... the possiblities are endless- i suppose you could do anything involving electric circuits since thats what the cbse calss 12 physics text covers most- i doubt ud want to do anything on ray or wave optics

i think it can freeze the motors inside and damage them, if it frezes then you would not be able to move them

I assume you mean something like a doorbell (even larger bells, like fire alarms, work the same way in general).\n\nWhen the button is depressed, a low-voltage signaling circuit is closed and current flows to a transformer. The transformer then closes in response to the signal, completing a high-voltage circuit. The transformer's job is to create a high magnetic field. This field than acts upon a hammer, draing it away from the bell. When the hammer contacts an open contact, the control circuit is opened, the transformer goes off, the magnetic field goes off. The hammer has a spring on it which pulls it back. It hits the bell. Ding-dong.\n\nThat's the simple version. Here's the longer version:\nhttp://home.howstuffworks.com/doorbell.htm
