Two ways exist to produce an electric field:

1. A changing electric field produces a magnetic field and a changing magnetic field that produces an electric field.

2. An electric field can be created by an isolated electric charge, in which case the field strength at a distance r from a point charge Q is given by
E= Q/4pi (r^2)e, where e is the permittivity of the intervening medium.
How does the process of a supernova work after it has turned into a Red Giant or White Dwarf or whatever, and it begins the rebirth process? Or accretion process? If Im correct Plasma is all thats left right? Just wondering if either of the two methods you mentioned could be at work?
