I want to start a project making an inductive guidance robot. I picked up a Velleman mk105 kit pretty cheap. It generates a 1 khz sine wave. I don't have an oscilloscope but my meter says its outputting a 168mv signal. I want to use this for the guide wire. I have 10mh inductors. I figured 168 mvolts wont hurt anything if I short it out. So I did with some wire to try to see if I could induce anything in the inductor and no luck. I think I need to amplify the signal so it can induce a voltage but I don't know how to do it. I know the more current I have going through the guide wire the bigger the magnetic field it'll create around the wire.
Also Do you guys know any formulas for inductors to figure out how much induction there will be?
