Ok, I was sucessful in verifying the law of induction. I took a 1.5 volt AAA battery a screw and about 22 turns of 22gauge copper wire. It was able to pick a tiny screw. My only question is way after I did the experiment was the screw still magnitized. It was like I created a weak permanate magnet. Does this just last for a few hours or something. If not , How do I demagnitize it. Without heating the crap out of it. Tried rubbing it but I am really not sure what to use if anything. Also I know you cann't magnetize copper. So if we didn't have a screw in between the coil of wire would it still make a magnetic field? I thought around any wire their is a magnetic field in the shape of circles around the wire. But with copper is their NO CIRCLES because their should exist a magnetic field around any wire that has current going thru it. So why doesn't copper have poles I thould if you have a magnetic field then you have a north pole and a south pole. No monopoles exist this can be seen by maxwells equations. Either their is no magnetic field around copper (which isn't true ) or the force vector's cancel out some how Could we use (instead of copper wire) iron or steal wire and wind it in coils with nothing inside it. And have it attract objects. Thanks for any clarity.
