A straight line carrying current in a magnetic field that is uniformly directed northward and vertically upward. The direction of the magnetic force is southward.
A magnetic force, attraction, nor repulsion is produced by the motion of electrically charged particles. It is the underlying force that causes phenomena like the operation of electric motors and the attraction of magnets to iron.
Magnets are continuous and form a perfect loop. Magnets' opposing poles attract one another while their like poles repel each other. At a magnet's poles, the magnetic lines of force are much more dense. Magnetic force lines that are parallel and move in the opposing directions cancel one another out.
