IntroductionMagnets have existed for hundreds of thousands of years and have been used by many different cultures during this time. Magnets have been useful over the years because they can hold two things together simply through the strength of the metal in the magnet. With technology evolving worldwide, electromagnets have evolved from magnets and are more useful than a regular magnet, but for an electromagnet to work, an electrical current must be present (http://saxonhomeschool.hmhco.com /ha/ Resources/saxonhomeschool/Holt_ST_PhysSci_Samp.pdf). The following questions that need to be addressed when learning about magnets and electromagnets are:1. What is a magnet?2. What causes magnetism?2. What are the different types of magnets?3. How are magnets useful?4. What is an electromagnet?5. How are electromagnets used today? What is a magnet? A magnet, defined in the Merriam-Webster dictionary, is classified as "a piece of iron (or a mineral, an alloy, or other material) that has its component atoms arranged in such a way that the material exhibits properties of magnetism, such as attract other objects containing iron or align in an external magnetic field” (insert quote for google) This definition says that a magnet contains a magnetic field and can attract other objects with similar properties of that magnet so that they combine with each other creating a pattern. constant grip. Magnets were discovered more than 2000 years ago when the Greeks found a mineral that bonded to similar objects made of iron. This mineral was discovered in a city called Magnesia, so the Greeks called it lodestone (insert Saxon quote). What causes magnetism?
