WebIn anisotropic materials such as minerals and rocks, the AC magnetic susceptibility is also anisotropic, and consists of two components, one in-phase with the applied field (ipMS) and the other out-of-phase (opMS). WebFeb 17, 2013 · Table 1 shows the magnetic susceptibility (a measure of the strength of the material's magnetic field) for a number of common diamagnetic materials. The susceptibilities of diamagnetic materials are all negative, indicating they generate a magnetic field opposite the direction of the external field. pontoon boat lifts manufacturerIn electromagnetism, the magnetic susceptibility (Latin: susceptibilis, "receptive"; denoted χ) is a measure of how much a material will become magnetized in an applied magnetic field. It is the ratio of magnetization M (magnetic moment per unit volume) to the applied magnetizing field intensity H. This allows a simple classification, into two categories, of most materials' responses to an applied magnetic field: an alignment with the magnetic field, χ > 0, called paramagnetism, or … pontoon boat lifting strakes kit
