    Hi guys, I m trying to replicate this version of a homemade magnetizer in the simplest way:
    http://rwgresearch.com/open-projects/10000j-cap-bank/

    Basically it consists in a bank of capacitors, but I have some questions he said he use 50 capacitors of 3,300uF and 350V DC, in the images seems connected in parallel and he said it can generates a maximum of 2958 volts with 800 Amps but according with the caps connected in parallel I don't see it possible since if it is connected in parallel the voltage would be the same 350v only the capacitance would be higher, How it is possible?

    Also he said, he use a contacter to discharge the capacitors in a very briefly period of time which it can be very dangerous, what it is a contacter? How to discharge the capacitors in a very briefly period of time?

    That is also the basis for a stud welder, the discharge is usually done with a high power SCR.
    A contactor is a industrial strength relay and used for that purpose would require a very specialized DC version with arc chutes and arc blow out of some kind.

    The project has nothing to do with magnetism. It simply makes a high voltage, very high current pulse.

    What it is a SCR? it is a silicon controlled rectifier? Can you explain why it is necessary to make the discharge done?

    He discharged the caps into a step-up transformer.
    As for why is it necessary to discharge the caps, what would be the point of charging them if you didn't intend to put them to work?
    If you value your life (or the lives of those around you) DON'T replicate this. Judging by the questions you are asking your inexperience could prove FATAL.

    Google SCR to find details, it is an electronic switch, that once turned on remains on until voltage has collapsed.
    IOW it dumps the charge in one shot.

    Yes Minder, I was google SCR and it is defined as silicon controlled rectifier, also I was google IOW but in this case and nothing appears in relation with this, I don't know what it means, anyway I m interested to build it in the simplest way, so for that the only thing that probably I need is the component able to discharge the capacitors in very few time, if really exists that electronic component. You was talking about IOW,if that is the component what it means IWO?

    @thew ... since it is obvious that you really don't know what you are doing .. you shouldn't be playing with such dangerous projects

    @Alec_t 's advice is the best advice you can take
