John, thanks for the information on the type of electrode. Thank you everyone for your input. Also, I didn't think to mention that the electrodes were simply to allow an electric flow so that I would be able to show the effects of a magnetic field on conducting fluids. My hypothesis is that the gallium should cool down after being exposed to the magnetic field. It wasn't to show the 4th graders that gallium conducts. I usually think outside the box before I know what is inside it, and it didn't occur to me. Too late now. Thanks. Maybe if this works out well I will post some of my final project on here.

Ok, I've never done this before (use a forum website). I'm in school and we have to conduct our own demonstrations for 4th graders. I am using liquid gallium an I want to pass an electric current through it using immersed electrodes. However I don't know what electrodes to use as I know gallium isn't exactly "friendly" with most other metals. I don't know what materials it might be friendly with. So what electrodes should I be using. I'm in middle school and very new to this.
