Primary magnetic field
WebWhen the magnetic Reynolds number is high enough, the induced magnetic field has a significant impact. Kumar et al. [14, 15] go into great length on the study of MHD free … Webin the primary coil results in surges of current in the secondary coil. The effect is stronger if both coils are winded around an iron ring. The primary coil creates a magnetic field that goes throgh the secondary coil, too. If the magnetic field changes with time, an electromotive force (EMF) develops in both coils.
