- TL;DR Summary
- Imagine two series coils carrying a Time varying current such that magnetic fields of both coils oppose each other, what will be the orientation and polarization of the Induced Electric Fields due to changing magnetic fields in the Space between the coils (circled by Orange Box in Fig. 1) ?
Will it be circular as shown by green arrows in Fig. 2 or will it be axial as shown by red arrows in fig. 3 ?
