magnets

In class we have been talking about magnets for sometime now. Before, i never realized how there are so much magnets in things that i use daily at home. I used to think that only things like a magnet you stick on the frig or freezer to hold things were important magnets. After learning so much about them i know that there are different types of magnets. There are electromagnets and permanent magnets. An electromagnet is a temporary one that gets magnetized. A permanent magnet is always magnetic. A magnet is an object that creates a magnetic field and exerts a magnetic force. It has both a north end and a south end where the charges are strongest on the ends. The different south and north ends attract to their opposite charges. For example if you had two magnets and you put them near each other, if the two ends closest to one another are the same charge, the magnets will repel one another but if they are the different they will attract and connect. A magnet can become ferromagnetic which means that their charges get algned within the magnet making them magnetized. There's alot to know about a simple magnet. Its essential to many things that operate electronically. Physics is everywhere!{the picture is of two magnets on my frig!=)}
