Ferromagnetic Elements: which metals from the periodic table experience strong attraction towards a magnet? Here are seven samples- 1 cm cubes of 99% pure elements: Ti (titanium), Fe (iron), Co (cobalt), Ni (nickel), Cu (copper), Gd (gadolinium), and W (tungsten)- which of these metals are ferromagnetic? Swipe once to check your answer, swipe twice to see how some are more strongly ferromagnetic than others. Although magnets are familiar objects, the physics of ferromagnetism is very complex and is described by the quantum mechanics of intrinsic particle spin and the specific electron configurations of solids and molecules.
