Having the temporal magnetic field data of the various spacecrafts and the approximate time of the passage of current sheet, how can one calculate the current near the current sheet?
I wonder if the theory of an infinite current sheet is valid here. See https://eng.libretexts.org/Bookshelves/Electrical_Engineering/Book%3A_Electromagnetics_I_(Ellingson)/7%3A_Magnetostatics/7.08%3A_Magnetic_Field_of_an_Infinite_Current_Sheet
