#235 In this video I continue looking at the magnetic hysteresis exhibited by magnetic cores and try to measure the phenomenon on a practical core. I go over the basic concept as well as the practical build of the test circuit, and after the measurement is performed I look at how the data can be processed and what sort of information can be extracted form it - like the core losses.
