Any suggestions on a good power source for an AC electromagnet?
I am building an AC electromagnet as a part of a science project. I'm unsure of what to use for a power source that will safe and function properly. The end result of the project should cause a metal ring to "jump" off of a pole and into the air.. To do this, I need to be able to charge the coil (it only needs to charge for a second, literally). So, if anyone knows of a source with some type of on/off switch or button, that would be great, but I am open to any and all suggestions!
