Web24 feb. 2012 · What is a Hysteresis Loop? A hysteresis loop (also known as a hysteresis curve) is a four-quadrant graph that shows the relationship between the induced magnetic flux density B and the magnetizing force H. It is often referred to as the B-H loop. From hysteresis loops, we can determine a number of magnetic properties about a material. http://www.autex.spb.su/download/wavelet/books/sensor/CH49.PDF

WebThe magnetization lags behind the applied field. This effect is known as hysteresis. The typical but exaggerated hysteresis behavior of a ferromagnetic material is shown in the figure below, where the magnetic induction B is plotted vs. the magnetic field intensity H, which is directly proportional to the current in the surrounding coil. WebIt is thus found that the magnetic flux B always lags behind the magnetizing field H, when H changes. The lagging of B behind H is called “Hysteresis” the closed curve ‘ bcdeefga’ which represents a cycle of magnetization of the specimen is known as the “Hysteresis curve “ of the specimen.
