... In situations where there is a variation in the current magnitude it is rather inadequate to define just the total current flow in the system. One can then use the current density as the primary parameter which is defined as the current flow per unit area. ...

... These materials are not attracted to magnets and cannot become magnets. In other materials, there are large areas where the north and south poles of atoms are all lined up in the same direction. These areas are called magnetic domains. Generally, the magnetic domains point in different directions, s ...

... Only a few Am stars are known to host a magnetic field so far and all of them have ultra-weak fields, with longitudinal components of less than 1 G (Petit et al. 2011; Blazère et al. 2015). If such an ultra-weak field were present in the Am component of HD 5550, it would have remained undetected in ...

Magnetochemistry
Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic. The magnitude of the paramagnetism is expressed as an effective magnetic moment, μeff. For first-row transition metals the magnitude of μeff is, to a first approximation, a simple function of the number of unpaired electrons, the spin-only formula. In general, spin-orbit coupling causes μeff to deviate from the spin-only formula. For the heavier transition metals, lanthanides and actinides, spin-orbit coupling cannot be ignored. Exchange interaction can occur in clusters and infinite lattices, resulting in ferromagnetism, antiferromagnetism or ferrimagnetism depending on the relative orientations of the individual spins.
