In electromagnetism and electronics, electromotive force (emf, denoted and measured in volts), is the electrical action produced by a non-electrical source. Devices (known as transducers) provide an emf by converting other forms of energy into electrical energy, such as batteries (which convert chemical energy) or generators (which convert mechanical energy).

Definition. The magnetization field or M-field can be defined according to the following equation: = Where is the elementary magnetic moment and is the volume element; in other words, the M-field is the distribution of magnetic moments in the region or manifold concerned. This is better illustrated through the following relation: = ∭ where m is an ordinary magnetic moment and the triple ...

Spinodal decomposition in the presence of a moving particle source is proposed as a mechanism for the formation of Liesegang bands. This mechanism yields a sequence of band positions xn that obeys the spacing law xn∼Q(1+p)n. The dependence of the parameters p and Q on the initial concentration of the reagents is determined and we find that the functional form of p is in agreement with the ...

Mar 05, 2014· However, the real challenge seems to be the separation of the magnetic nanoparticles from water once the adsorption has taken place, what has been called the separation problem. Dr. Frank Hutter from the Fraunhofer Institute for Silicate Research (ISC) in Germany has studied magnetically separable nanoparticles exhaustively and has recently ...

Jun 22, 2018· There are two common ways to distinguish mirror-image molecules, or enantiomers. The first relies on their distinct interactions with circularly polarized light, the second on their interactions with a pure enantiomer of some other molecule. Now Banerjee-Ghosh et al. report a conceptually different approach to chiral resolution. Experiments showed that, depending on the direction of ...

A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials. A charge that is moving parallel to a current of other charges experiences a force perpendicular to its own velocity. The effects of magnetic fields are commonly seen in permanent magnets, which pull on magnetic materials (such as iron) and attract or repel ...
