Good evening mam I am finding very difficult , the difference between stationary & progressive wave Kindly make a video on it As it is a very important question & nice video mam 🥰😊

Good wishes mam I have a doubt, while watching the video. It is that why is the magnetic permeability of non magnetic substances is taken as unity? Kindly clear this doubt 🙂

It’s relative permeability beta that is one

@@sarbdeepkaursidhu4155 yes mam, but why relative permeability is unity (1)for conductors & non magnetic materials? Plzz tell for each of them Thank you
