Effect of Neutral Conductor on a Point Charge?

AI Thread Summary
The force on a point charge is directed toward a neutral conductor due to the movement of charges within the conductor. When a positive point charge is near the neutral conductor, the negative charges in the conductor are attracted and move closer, creating a net force. This concept highlights the ability of charges in a neutral conductor to respond to external electric fields. Understanding this interaction clarifies how neutral conductors behave in the presence of point charges. The discussion emphasizes the importance of charge movement in explaining the forces at play.

Why should the force on a point charge always be toward a neutral conductor? I know this is a simple concept, but I'm having trouble grasping it.

Any ideas?

Thanks!

Because a neutral conductor has both positive or negative charges which can move. If you have a + point charge, the - charges in the conductor move towards the + point charge and there is a net force.
 
Oh, ok. I never thought of a neutral conductor in that way, but that makes a lot of sense! 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 '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.
