What does hysteresis behavior mean?
Hysteresis is the dependence of the state of a system on its history. Hysteresis can be a dynamic lag between an input and an output that disappears if the input is varied more slowly; this is known as rate-dependent hysteresis.
When can you say that there is an observed hysteresis in the temperature readings?
If you pay close attention to your AC unit (set, say, to 78 degrees), you may notice that it turns on when the temperature rises to 79 degrees and off when the temperature falls to 77 degrees. This behavior is called hysteresis, and AC units are designed this way deliberately.
How does a hysteresis work?
Hysteresis loops happen when you repeatedly wiggle the system back and forth (cycle the field up and down). The magnetization of a tape will “lag behind” as the field sweeps up and as it sweeps down. The memory in the tape is the magnetization remaining as the field is released to zero from a large value.
What does the hysteresis loop represents?
A magnetic hysteresis, otherwise known as a hysteresis loop, is a representation of the magnetizing force (H) versus the magnetic flux density (B) of a ferromagnetic material. This hysteresis loop therefore summarizes the pathway that a ferromagnetic material takes from the addition and removal of a magnetizing force.
What is meant by hysteresis and hysteresis loss define hysteresis curve?
Definition: The work done by the magnetising force against the internal friction of the molecules of the magnet, produces heat. This energy which is wasted in the form of heat due to hysteresis is called Hysteresis Loss.
What is hysteresis explain the hysteresis curve?
The hysteresis loop shows the relationship between the magnetic flux density and the magnetizing field strength. The loop is generated by measuring the magnetic flux coming out from the ferromagnetic substance while changing the external magnetizing field.
What is the difference between counter-clockwise and clockwise hysteresis?
Counter-clockwise hysteresis has been generally defined as the process in which effect can increase with time for a given drug concentration, while in the case of clockwise hysteresis the measured effect decreases with time for a given drug concentration. Hysteresis loops can occur as a consequence of a
What is the medical definition of hysteresis?
Medical Definition of hysteresis. 1 : the lagging of a physical effect on a body behind its cause (as behind changed forces and conditions) all manometers must be tested for hysteresis as well as for sensitivity and natural frequency — H. D.
What is the anticlockwise hysteresis loop?
Anticlockwise hysteresis loop (i.e. lag effect) Concentration–response measurements are made at various times after a dose. The arrows show the direction of time Plasma concentration R e s p o n s e 1 Clockwise hysteresis loop (i.e. tachyphylaxis and tolerance) Concentration–response measurements are made at various times after a dose.
What is a hysteresis curve?
The closed figure a c d e a is variously called a hysteresis curve or diagram or loop. The effects of temperature upon hysteresis were also carefully studied, and many hysteresis loops were plotted.
