About the magnet strength comes from god

Magnets were drawn to the side of the refrigerator, the earth's gravitational pull it down, so the magnet must be overcome gravitational energy, then its power come from? Let us first analyze the stress state of magnets. When profile fridge magnets are attracted to, it is static. According to Newton's first law of motion, the resultant force is zero on the fixed object. Through the simple analysis, we may safely draw the conclusion that, in this state, magnets are four force, namely, magnet and electromagnetic force between the refrigerator side ( This is two forces) , gravity and the friction between on both sides of fridge magnets. The four force opposite to each other and balance each other, so the magnet is static. Therefore, we may draw a conclusion that: 'was the side of the adsorption in the refrigerator magnet, and decades not drop'. This phenomenon is the phenomenon of force balance, the reason comes from the competition between gravity and electromagnetism, the magnet electromagnetic force come from? Here, we have a simple science. The atom is composed of atomic nuclei and electrons. Nuclei are positively charged and electrons are negatively charged. From inside the atom, the electron, which is moving around the nucleus and constantly rotating. Because of the moving charges will form current and magnetic field, so the movement of the electrons will produce magnetic field. In most materials, the electronic sport is chaotic.
