I need to create a current of electricity that switches polarity with a frequency of 83.5 Kilohertz, then step that up in voltage without losing that frequency. Any ideas on how this may be done?

I can't think of the IC off the top of my head, but one of the LM series can be purchased in various increments of frequency. So you can get a low voltage, low current oscillations made, but then you'll need some additional amplifier and why do you want to run it through a transformer? Feel free to message me direct maybe I can come up with a solution rather than do actual job related work :-)

If you search for "555 timer" you'll get lots of discussions about a common chip that can be used to create a frequency. That would be the astable mode. It's generally used for lower frequencies. I think the capacitor would have to be a low leakage type for ~80KHz.
This is a starting tip only. It'll require some experiments.

there are frequency generators on the market, or you could build one if you have any bace frequency and a strong backround in electronics. (probably not)
You'd use any amplifier to step up the power without changeing the frequency
