Hi Everyone, This is Sentil from India. I'm a professional in the field of commerce. But i love science!! then the obvious question "Why /How did you end up in Commerce". Thats really a long story. But today im here to get help on one of the side projects i am into to develop something like "solenoid in reverse". That is, i want to generate some power from the solenoid by mechanically moving the plunger of the solenoid. I did some basic web research ( i still do ) and together with my lil elementary science knowledge, i understood how solenoid works and what is the principle and all the theory part. but i cant find anything on this " Solenoid in reverse" or "reverse solenoid" ( not sure if im confusing you guys. this device is suppose to work just like "linear alternators") like no of turns of copper wire, how powerful should be the magnet, what should be the speed at which this magnet should move to and fro to cut the magnetic flux and generate output power. It would be very help if somebody could help me with these doubts and help me build one. Looking forward to hear from you all..!! Thanks Sentil P.S:- Do i need to post this somewhere else?
