When two magnets are positioned on opposite sides of a table, moving one magnet causes the other to move due to the magnetic field interaction between them. This phenomenon can be explained by the principles of magnetism, particularly the concepts of magnetic force and field lines. The force exerted by one magnet on the other is governed by the inverse square law, which states that the force decreases with the square of the distance between them. Understanding these interactions involves applying formulas related to magnetic fields and forces, which can be found in resources like Wikipedia. Overall, the movement of one magnet affects the other due to their inherent magnetic properties and the forces they exert on each other.
