PPT-Magnetism

What is magnetism Force of attraction or repulsion due to electron arrangement Magnetic forces are the strongest at the poles Magnets have two poles North and South Magnetic poles and fields Magnets always have two poles. 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.. p. erovskite. oxides. Phillip Barton. 05/28/10. MTRL 286G. Final Presentation. Comparison of 3d and 4d magnetism. 3d transition metals Fe, Co, and Ni are ferromagnetic, however no 4d or 5d are ferromagnetic (except reports of . Intro video. Properties of Magnets. They attract ferromagnetic materials. Iron, nickel, cobalt. They have magnetic poles. Like poles repel. Opposite poles attract. Magnetic Poles. Magnetic Fields. The area .
