Charge Conservation & Isolated Systems

AI Thread Summary
In an isolated system, the total charge remains constant, even when high-energy gamma radiation causes pair production of an electron and a positron. While the number of charged particles increases, the algebraic sum of their charges remains zero, as the electron has a charge of -1 and the positron has a charge of +1. This illustrates that charge conservation pertains to the total charge, not the total number of charged particles. Therefore, the principle of charge conservation holds true in such scenarios. The discussion confirms that the focus is on the algebraic sum of charges rather than the quantity of charged entities.

A isolated system in which number of charges present is always constant. Suppose a high energy gamma radiation enters into the isolated system and produces positron and electron (pair production), now the total number of charges present in the system increases right? Then how the charge conservation is true?

The total charge is conserved, not the total number of charged particles. An electron carries a -1 charge. A positron carries a +1 charge. The total is still zero.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
