AI Thread Summary

The discussion centers on understanding the E-field of a moving charge at constant velocity, specifically the role of the Lorentz factor, gamma(u). The Lorentz factor is crucial in special relativity and affects how the electric field behaves as the charge moves. When the charge moves slowly compared to the speed of light (c), its electric field closely resembles that of a stationary charge. This highlights the relationship between charge velocity and electromagnetic fields. Understanding these concepts is essential for grasping the behavior of moving charges in physics.

I came upon this page that provides the answer:

But I can't figure out what gamma(u) is. Could anyone help?

That's the usual Lorentz factor of special relativity. See: Lorentz factor

Thanks. So if the charge is moving slow compared to c, then the field resembles that of a stationary charge.

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.

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 'Do Electrons Completely Leave a Capacitor at T/4 in an LC Circuit?'

Hello. My question is: When a capacitor in LC circuit is out of charge (T/4) does that mean that all electrons left the capacitor or that there is the same quantity of electrons on both plates?
