Magnetism (Revised) (15:29)Magnets can be found in many objects that we use everyday. Not only are they located in man-made objects, but magnetic materials can be found in nature as well. In fact, the mineral, magnetite, was found to have magnetic properties long before humans learned how to make magnets on their own. By viewing the video and discussing the concepts presented, students will enhance their knowledge about magnetism. The video presents general information about magnetism, as well as concepts about atoms, and the relationship between electricity and magnets.
