Webb1 juli 2024 · The existence of at least one unpaired electron spin in a material’s atoms or molecules causes paramagnetism. To put it in another way, any substance with atoms with partially filled atomic orbitals is paramagnetic. The unpaired electrons have a magnetic dipole moment due to their spin. WebbParamagnetism is due to unpaired spins. Nucleon spins, the basis of NMR spectroscopy, have a small angular momentum compared with that of the larger electrons, and is normally ignored when considering the paramagnetism arising from electrons. Electron spins produce a large effect.
