MAGNETISM When you bring home an A plus paper where do you put it On the refrigerator of course You grab a magnet and the paper stays up for everyone to see But how does it stay up The answer is magnetism Magnets can be used to hold items in
Magnetism THINK ABOUT IT is a natural force Magnetism is a force of that can either nature or something that bring certain metal happens without any known objects together cause Can you think of any like a magnet and other forces of nature a refrigerator door or keep them apart Some rocks and metals contain this power naturally Magnetism is an invisible force it can be felt but not seen Scientists study magnets observing how they behave Magnets can be simple to understand how objects used to hold items on a refrigerator or they can be magnetism works parts of large complicated
INSIDE a MAGNET Everything in the world is made up of tiny units called atoms Inside atoms are protons neutrons and electrons When electrons spin around the center of the atom tiny magnetic forces are created If most or all of the electrons spin in the same direction the HW magnetic forces join An artist's view of together to make electrons spinning around the center of an atom a magnet 6
Magnets can be made by rubbing a piece of metal in one Atoms are what direction against an existing scientists call the magnet many times The spinning units that make electrons in the metal are pulled up all matter by the magnet in one direction The center of an which creates magnetic force atom is called a nucleus Running a needle over a bar magnet makes the needle magnetic
