Definition of "Hysteresis" |
A physical phenomena wherein the path followed during relieving an applied stress lags that during applying the stress, so that on complete removal of the applied stress a strain remains. This particularly occurs in magnetic materials - the lagging of induced magnetism behind the magnetizing force. / The time lag of the magnetic flux in a magnetic material behind the magnetizing force producing it. Caused by the molecular friction of the molecules trying to align themselves with the magnetic force applied to the material. The property of a magnetic material which causes the magnetic induction for a given magnetizing force to depend on the previous conditions of magnetization. / A physical phenomena wherein the path followed during relieving an applied stress lags that during applying the stress, so that on complete removal of the applied stress a strain remains. This particularly occurs in magnetic materials the lagging of induced magnetism behind the magnetizing force. / Hysteresis is the dependence of the output of a system not only on its current input, but also on its history of past inputs. The dependence arises because the history affects the value of an internal state. To predict its future outputs, either its internal state or its history must be known. If a given input alternately increases and decreases, a typical mark of hysteresis is that the output forms a loop as in the figure. / When an electrode system is returned to a solution, equilibrium is usually not immediate. This phenomenon is often observed in electrodes that have been exposed to the other influences such as temperature, light, or polarization. / Alternatively referred to as internal memory, main memory, and primary memory, primary storage is a storage location that holds memory for short periods of times while the computer running. For example, computer RAM and cache are both examples of a primary storage device. This storage is the fastest memory in your computer and is used to store data while it's being used. For example, when you open a program data is moved from the secondary storage into the primary storage. / (1) the phenomenon that the magnetic state of a substance is dependent upon its magnetic history, so that its magnetization for an increasing magnetizing force differs from that for a decreasing magnetizing force. |
