Wire its coil in series with one of its normally closed contacts to the supply

So, then( if im right) you can make another circut hooked up to the switching terminals, and make it pulse dc current, or make a very crude ac current.

Yes, in the very eary days of car radios, AC for their internal high violtage generations was supplied by "vibrators", which are essentially what we have here.

Thankyou for the schematic. I have asked other people about how to wire a relay like this, but no one would answer me. So i just asked about oscilators in general.

Run it off AC.

Well, my whole point is so that i can turn the dc current from a battery, into a very crude version of ac.

To get square wave AC, you can use a 3pole/dual throw relay. Set up one of the poles as Steve says to make it oscillate.

Connect your input voltage to the NO of one of the free poles, and the NC of the other. Connect 0V to the remaining NC and NO. You will now have something which resembles AC across the commons.
