Web30 sep. 2024 · Inductively induced polarization is most pronounced when a conductive polarizable layer overlies a resistive nonpolarizable base. In this case, at a certain thickness of the layer, the IIP effect far exceeds that observed in the presence of a thick polarizable layer and even of a homogeneous polarizable half-space. WebThe induced polarization (IP) geophysical method has been widely used for mineral exploration. This method makes it possible to estimate not only the resistivity …
WebSpin polarization of electrons or of nuclei, often called simply magnetization, is also produced by the application of a magnetic field. Curie law is used to produce an induction signal in Electron spin resonance (ESR or EPR) and in Nuclear magnetic resonance (NMR). Spin polarization is also important for spintronics, a branch of electronics. WebThe polarization process always involves the use of a charged object to induce electron movement or electron rearrangement. In the above diagram and accompanying …
