Explain hysteresis loop
WebApr 12, 2024 · The hysteresis loop observed in this case was the same as that in the presence of laser pulses in both cases. In our case, the memory effect weakly depends on the erbium concentration. For this reason, we believe that memory is due to a local change in the properties of the crystal environment of the impurity ion rather than to the formation … WebAboutTranscript. Ferromagnets with high retentivity and coercivity are used as permanent magnets (hard magnets), while the ones with low retentivity & coercivity (soft magnets) are used as cores in electromagnets. But all ferromagnets have high permeability. Let's explore these differences between the permanent magnets and the ones used in ...

Webconcentrations of gallic acid (GA), hysteresis or ‘ bistability ’ has been observed. At higher GA inflow concentra- tions a sequence of simple and mixed-mode oscillations is found between the two stable steady states at long and short residence time. A new form of complex waveform is also reported. The mechanistic characterisation
WebUnlike the constant on-time and the constant off-time control, in which only one current command is used to limit either the minimum input current or the maximum input current, the hysteresis control has two current commands, ihcmd ( t) and ilcmd(t) (ilcmd(t) = δihcmd ( t )), to limit both the minimum and the maximum of input current [ 25–28 ].
