Understanding Electric Charge: Is it Just Electrons?

AI Thread Summary
Electric charge is not solely comprised of electrons; it can also include positively charged particles like protons. A coulomb represents the charge of approximately 6 x 10^18 elementary charges, which can be either negative or positive. The definition of a coulomb predates the discovery of electrons, indicating that electric charge encompasses more than just these particles. In modern physics, electric charges are linked to a variety of particles that interact with electromagnetic fields. Understanding electric charge requires recognizing this broader spectrum of charged particles.

I was reading my physics books. And then a question came across my mind.
Now here the the definition of coulomb. Electric charge measured in units of coulombs. It takes about 6*10^18 electrons.

So the question is did the electric charge only consists of electrons.

No, it doesn't have to be electrons. A Coulomb equals the magnitude of the charge on that many elementary charges, which may be negative (like electrons) or positive (like protons).
 
When the unit is defined, the electrons were not even discovered. Therefore, it highly likely not. In fact, in modern physics, electric charges are associated with particles that interact with EM fields which have a whole family of them.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.
