Measuring the Hysteresis & Saturation Flux of one of my Magnetic Cores

A B-H chart shows the current applied to a coil on the X axis, and the field the coil produces on the Y axis. This can be used to determine things such as the permeability, hysteresis, and saturation flux of the core material.
I've been trying to successfully measure a BH curve for a while now, so I'm really happy about this. Expect to see more about this in an upcoming video.

very good, how you make it please explain
