Paramagnetism refers to a property of materials that are weakly attracted to a magnetic field.What is antiferromagnetism and paramagnetic material?
In antiferromagnetism, the magnetic moments of molecules or atoms align in a pattern in which neighbor electron spins point in opposite directions, but the magnetic ordering vanishes above a certain temperature. Paramagnetic materials are weakly attracted to a magnetic field.How do you know if a material is paramagnetic or diamagnetic?
If the electron subshells are completely filled with electrons, the material will be diamagnetic because the magnetic fields cancel each other out. If the electron subshells are incompletely filled, there will be a magnetic moment and the material will be paramagnetic.What is the relative permeability of a paramagnetic material?
The relative permeability is slightly greater than 1. The field inside the material is greater than the magnetizing field. Magnetic field lines become denser inside paramagnetic substances. Magnetization of paramagnetic substances is inversely proportional to absolute temperature.
