PPT-Chapter 21: Magnetism What is a magnet?

A magnet is anything that carries a static magnetic field around with it A magnet has a North and South pole Magnetic lines of flux make up the magnetic field and travel from North to South outside of the magnet. Magnetism is the property of attracting iron by a magnet.. A magnet is an object made of certain materials like iron which can create a magnetic field around it. If there are things made of iron in this field (region) they are attracted by the magnet.. THE SCIENCE OF MAGNETISM. . In this video, students in grades 5 through 8 join Disney . Imagineer. , . Asa.
