Given a magnet that is free to rotate in an external magnetic field, which way will it line itself up? Draw your answers in paint (i.e. draw the field lines, and draw the final position of the magnet with the poles labeled). Do four different examples: magnetic field up, magnetic field down, magnetic field left, magnetic field right.

You don't have to draw each one out but I just don't understand what this question was asking. If someone could just explain to me what my professor is wanting for this question.

Answer #1

It means in an external pointing magnetic field how a magnet will orient itself. Magnetic field lines originate from the north pole and terminate in the south pole. By seeing the field lines and where it is pointing, we can assume where is the north and south pole of the external field is lying. So, if a magnet is placed in such field, it will always orient itself so that its its north pole gets near to the south pole of the external and its south pole gets near to the external north( opposite poles attract).

I am showing two examples of this. Hope you will get.
