These are some magnets that are attached to my fridge. I have them to hold other things on my fridge in place and so they do not fall. The reason why I am talking about magnets is because they are closely related to how an atom works. Two like charges repel each other, while on the other hand two opposite charges containing a neutral, positive, or a negative will attract each other. This meaning that if two positive charges were to be combined, they would repel each other and go away from each other. If a positive and a neutral charge were to be combined, then they would attract each other. This is how a magnet works. The charge between the fridge and the magnet are opposite, therefore they are attracted. This explains why the magnet is able to hold itself up on the fridge.
