From my other book I take this topic: Negative signs in Gauss law make Faraday law symmetrical?; Post-Comment #1998 of 5th ed
I am going to start the first page of the Advanced text
In this book of True Calculus, I have a advanced-text section which will discuss the Maxwell Equations.
Here I am trying to make them symmetrical.
So if I have my negative signs placed correctly, I will have made the 8 original Maxwell Equations of 1861 into 10 equations for which they are fully symmetrical. I accomplish this with magnetic monopoles and where electric charge has like repel and unlike attract, while monopoles are attract only, regardless of like or unlike.
So, using this website I am going to try to fill in the extra 2 equations that Maxwell missed:
