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. Often cheap relative to other geophysical techniques.. Can be measured with ground-based or airborne equipment.. Not usually very useful when looking at sedimentary structures. (We’ll see why later!). Magnets. permanent magnets. e. lectromagnets. t. he Earth’s magnetic field. magnetic forces. applications. Magnetism. 2. Magnetism. two sources of magnetism. permanent magnets. Electromagnets . (currents in wires). Magnetism day 1. What causes magnetism?. How is magnetism linked to electric charges?. Magnetic fields come from . moving. . charges. . a moving charge around an atom produces a magnetic field. currents in wires will produce magnetic fields. simple electrical circuits – direct current DC.
