Question

You must explain why to get points!!!

Suppose we are in deep space so that there are no other forces to worry about. I have a 2cm long bar magnet ( this is the 1st magnet ) fixed in place at the origin of a coordinate system with its north pole pointing along the positive x-axis. I am holding an identical magnet at a point 100cm along the positive x-axis with its north pole pointed in the +y direction ( this is the 2nd magnet ). When I turn the 2nd magnet loose it will float freely except for any magnetic interaction with the fixed magnet. What will happen when I let go?

Explanation / Answer

a. The 2nd magnet will be pulled in the -x direction.
--------------------------------
First, the 2nd magnet will rotate and its north pole pointing along the positive x-axis and therefore two magnets will attract each other and the 2nd magnet will be pulled in the -x direction.
