Well, thanks for the input, i guess you really just summarized why i posted in the first place. I wanted to know if there is a solid state method of doing what i want to do. To be able to switch capacitors in and out of a circuit at preset current levels. Also, correct me if I am wrong, but...

I'm working on (building) a small induction generator setup. Its still well into the testing phase and i have a, what i think is anyways, rather complex question. I know that the output characteristics (voltage and line frequency) of the generator at a given load is proportional to the...

im still u clear why you only get shocked when you touch the live(hot wire) and other the ground or the neutral. If u touch the neutral and the ground nothing will happen. I asked my grandfather this(he was an electrician) and he can't really explain AC to me, but he did verify that you do not...

pretty much

ok, but how does the current change direction in AC, if it were to change direction as you say the 2 wires would alternate between pos and neg polarity and the direction changes, so if i had a loop made of some AC cable, the electrons would flow clockwise for half of the 60hz, and counter...

my bad about the current got a bit mixed up, ok, so higher current lower volts, but won't i need a thicker wire to carry the higher current? (i currently have very very thin wire), and if i were to let's say run 30volts at 10 amps, what gauge wire would you recomend?

that seems a bit overkill just to make an electromagnet(unless u need it to be super powerful with the very least amount of energy), anyways out of all the common materials you can easily get, iron is best

no one have any thoughts on the powersupply also which would be better to create a strong magnetic field; high current low amps, or height amps low current

well, I am probably not as experienced as other people on this forum, but ill give my 2 cents For the core, i think iron would be the best, it has the highest magnetic permeability, so you will get the strongest electromagnet possible, without using too much power in the coils. An ironm bol...

would anyone else know forsure about the powersupply? and thanks willib for that site

how fast/far did the magnet go? (roughly), and where can i get magnets like that. Also are there any other good types of objects that would work as a projectile. Regarding the powersupply i obtained, i just realized that it is a switching powersupply, like thoes used in PC applications...

thx, but as for the magnets, wouldent the positive pole of the magnet be attracted to the side of the solenoid because when it is powered the inside becomes negative?, would a long slender rod with let's say 4 strip magnets attached around it work( neg side facing away from the center of the...

thanks for the advice, i talked to a friend of mine who is a little more experienced in matters of power supplies than i am, and he was able to supply me a power supply of a more reasonable output, 40 volts at 3 amps, But as for the actual solenoid, since i was unable to locate a sutable...

Im building a big solenoid for my physics ISU and i was woundering on how it should be designed. I plan on supplying around 100-200 volts DC to it, at very low current, maby 2-7 amps. The question is this, does the solenoid have to have a specific length or number of coils, or a certain...
