What is hysteresis?
Q: What is hysteresis?
A: Hysteresis is a concept in physical science where the output of a system depends not only on its input, but also on its history of past inputs.
Q: Why does the history of past inputs affect the output of a system in hysteresis?
A: The history affects the value of an internal state which can affect the output of a system.
Q: What is required to predict the future outputs of a system in hysteresis?
A: To predict the future outputs of a system in hysteresis, either its internal state or its history must be known.
Q: What is the effect of hysteresis?
A: In hysteresis, there can be a lag between input and output which affects the system's output.
Q: Does the effect of hysteresis disappear as input changes more slowly?
A: Yes, the effect of hysteresis disappears as the input changes more slowly.
Q: What is rate-dependent hysteresis?
A: Rate-dependent hysteresis is a type of hysteresis where there is a lag between input and output that disappears as the input changes more slowly.
Q: In what materials does hysteresis occur?
A: Hysteresis occurs in ferromagnetic materials, ferroelectric materials, and in the deformation of some materials like rubber bands and shape-memory alloys.
