Oxygen ion energization observed at high altitudes
... The event used in this study is recorded by the Cluster spacecraft. The event is selected from a larger data set including CIS CODIF data over a 3-year period (January to May in 2001 to 2003) of oxygen ions (O+ ). This corresponds to orbits with apogee on the sunward side of the terminator plane. Ou ...

... • One henry is the inductance of a coil when a current, changing at a rate of one ampere per second, induces one volt across the coil. Most coils are much smaller than 1 H. • The effect of inductance is greatly magnified by adding turns and winding them on a magnetic material. Large inductors and tr ...

... A changing current in a loop of wire gives rise to a changing magnetic field (predicted by Ampere’s law) which can induce a current in another nearby loop of wire. In the this case, nothing observable (to your eye) is moving, although, of course microscopically, electrons are in motion. Induced em ...

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.
