What do I have2do2a wire2let me power a9v thing from a outlet? Can a9v battery clip only carry 9v? Screw terminal uses? Answered

I'm trying to invent something. I'm realistic enough to know it probably won't work as planned and definitely won't make me rich, but I'll always regret it if I don't try.

I need to power 6 electromagnets and I want to use one cord to power them.

The electromagnets are wire wrapped around a soft iron core. They don’t need to be strong, just strong enough to activate a reed switch.

(The pictures are labelled with #s to show which question they are for.)

1.
How do I connect them all into an electrical extension cord?
Do I have to use a screw terminal?

2.
Can a 9 volt battery clip carry more than 9 volts, or will it fry? If I properly joined a power cord and 9 volt battery clip and plugged it in, what would happen?
Would there have to be resistors? What kind?

3.
Would this configuration with two screw terminals work? Did I misunderstand the function of the screw terminal? Is there something better I could use?
(From bottom to top)
~The electrical cord powers the whole thing. It distributes the current to all the wires.
~The reed switches prevent the all wires from sending all the currents to the light bulb.
~If I put a magnet over the AQUA wire reed switch, the circuit would be completed and current would reach the light bulb and cause it to light.

I tried to figure out how to do it on my own but when you don't know any electric components, terms, phrases, and definitions - like me - it's next to impossible to look things up.

I'm with AndyGadget and Re-design, don't just go plugging wires into the mains power. Forget about the raging fire, you or someone else will die.
Listen to these guys, they know what they are talking about. If you are not sure , don't do it.

Use a powerstrip with 6 outlets and the appropriate wallwarts. Do not under any circumstances connect your 9v octopus-thingy to mains voltage. A raging housefire is the best case scenario with that device.

Thanks everyone.  I thought that 9 volts in an outlet was a bad idea, but this was the only way I could think of to find out without trying it.

What about the third picture?  Can screw terminals do that? (The device that is ultimately powered is an electromagnet - not a lightbulb.)

I'm not quite sure I understand the third picture. Can all of the wires potentially power the magnet, or just the aqua pair? It looks like all of the wires could carry power if their reed switch was activated - is that what you intended? I just ask because you specified AQUA in your example.
The screw terminals could work for this, depending of what the back of the terminal block looks like. I assume that the two long rows are electrically connected, i.e. one of each color wire is on the red half of the circuit, and one of each color is on the black half.
IF  all of the screws on the top row are connected together by a metal strip, AND all of the screws on the bottom row are likewise connected to each other, AND the red wire is connected to one row AND the black wire is connected to the other row, then closing any one reed switch will cause power to flow through the circuit and energize your magnet.
I know that you are working on an invention so you may not want to talk about the details, but if I had some idea what the invention was supposed to do, I might be able to offer better suggestions. I'm a glass artist, a theatre tech and a costume maker, so I really have no interest in stealing an electronics project (not that the electronics-guru-type folks on this site would steal your stuff either, BTW - and they'd definitely give you better info, but I can only volunteer myself). Please feel free to IM me if you'd like to bat ideas around.

I should probably add that it would be easier just to skip the screw terminals entirely and just solder all the wires together at the ends.

I'm not sure what you're trying to do here, but your setup looks INCREDIBLY DANGEROUS - do not plug your battery clips into the socket under any circumstances.
As Re-Design suggests, use a wall-wart adaptor (9 or 12 volt) to reduce the potentially lethal mains to a safe voltage.

Get a 9. volt d/c wall wart (adapter)  Get the polarity right and just plug the things in and you're ready to toss out those expensive batteries.

Yep, that's pretty much the best way to go about it.
