Hi everybody! As I understand when you face two magnets by the same
pole, no matter if one of the magnets is very weak, they always get
rejected between them.
Well, guided by this premise, I tried to achieve this objective, but
replacing the weak magnet by a weak electromagnet, with an "I" shaped
ferromagentic core, and 15 meters of 36 number gauge used for the
coil, and supplied by a 9 volts battery. I must to clarify that I made
several experiments by changing the cross area of the core, but using
always the same lenght of wire (because I need to obtain in every
experiment approximately the same DC resistance). Obviously the
resulting number of turns is smaller when higher cross section is
used.
Ok, so the question is, no matter which cross section you use =BFwhy
always electromagnet get attracted to the magnet?
I=B4m sure that they are faced by the same pole when I perform the
experiment and electromagnet works properly, the only thing is that
its power isn=B4t too much; so finally, Is the problem here that the
mentioned premise doesn=B4t apply to magnet-electromagnet interaction?
