Currently the South mar 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 . 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. 1 How How do we knowdo we knowabout the about the EarthEarth Oceans cover _____% . of Earth’s surface (all water =75%). 71. 5 oceans. smallest. Largest & deepest. NEW.
