Hello! Here is what our scientists have to say to your question: Magnetic permeability of free space (or magnetic constant) μ0 is a constant defining the relationship between magnetic field strength H (A/m) and magnetic flux density B (T) in a vacuum. On the top right corner slide 8, the Landau-Lifshitz(LL) equation is written with B, while two next equations use H. To combine these equations, we introduce mu0 in LL. Moreover, both systems of units: CGS and SI are used in the lecture in parallel. Thanks for watching!
Can someone help, where does mu0 come from around 12:00
