Diamagnetic hysteresis loop

WebFeb 24, 2012 · 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. WebSome well known diamagnetic substances, in units of 10-8m3/kg, include: quartz (SiO2) -0.62 Calcite (CaCO3) -0.48 water -0.90 2. ... This behavior is called hysteresis and a plot of the variation of magnetization with magnetic field is called a hysteresis loop. Another hysteresis property is the coercivity of remanence (Hr). This is the reverse ...
