 * 1) The field produced by an electric charge is radial, and so the force is radial: two electric charges will either push each other away or pull each other together (like charges repelling and opposite charges attracting). And the same is true for magnetic monopoles - but real-world magnets are dipoles, not monopoles, and thus are a bit more complicated.
 * 2) For any object, you can pick a frame of reference in which it is stationary, and in any other frame of reference it is moving. That magnetic fields are only produced by, and only act on, moving electric charges, simply means that the magnetic field also depends on your frame of reference.
