Then why do you need to know the area of the hysteresis loop?SDRFG said:how to use calculus here i have never done .
Then why do you need to know the area of the hysteresis loop?
SDRFG, can you attach a neat plot of your hysteresis loop, with the measured points clearly shown?SDRFG said:How to drawn second degree polynomial, like this?
Please attach your plot.SDRFG said:i want to learn by hand in paper
That's okay. It's obviously a matter that piqued your interest at the time, and you kept it in mind should the opportunity later present itself to pursue it further.SDRFG said:I don't have any plot it was in college i left it over 3 year completing degree. they dnt guide properly may be lack of information.
At class i was not aware of it, but while teaching for few days on it it attract me.Here's your opportunity. What would you like to do in this thread at this point?
The area of hysteresis refers to the enclosed region in a graph of a material's response to a changing external stimulus, typically plotted as a loop. It is a measure of the energy dissipated during one complete cycle of the stimulus.
The formula for calculating the area of hysteresis varies depending on the type of material and the nature of the external stimulus. In general, it involves integrating the curve of the material's response over one complete cycle. For example, in the case of a magnetic material, the formula is: A = ∫H*dB, where A is the area of hysteresis, H is the magnetic field, and dB is the change in magnetic flux density.
The area of hysteresis provides valuable information about the behavior and properties of a material. It can indicate the amount of energy lost in a cycle, which can affect the efficiency and performance of the material in various applications. Additionally, it can reveal the degree of nonlinearity and hysteresis in the material's response, which can impact its reliability and stability.
The area of hysteresis can be measured experimentally by using specialized equipment such as a hysteresis loop tracer or a vibrating sample magnetometer. These instruments apply a varying stimulus to the material and measure the corresponding response, allowing for the calculation of the area of hysteresis.
The area of hysteresis can be influenced by various factors, including the composition and microstructure of the material, the magnitude and type of external stimulus, and the temperature and environment in which the material is tested. Additionally, the presence of impurities, defects, and mechanical stresses can also affect the area of hysteresis in certain materials.
