I am a grade 12 student, working with electromagnets for a physics project. My equation requires me to measure the current of a 20-25 cm bare copper wire 18 gauge. The power supply would be an aaa battery (1.5v) and a rechargeable aaa battery (1.2v). How much current can I expect from this battery (completely new, haven't even taken it out the box)with neodymium magnets (which conduct) on both the positive terminal and the negative (one on each side of the battery basically). I haven't really dealt like this with anything before but I want an approx value so that I can test this equation out.
Edit: The circuit would be 20-25cm long
