Are there any planetary systems that are influenced by EM waves?

AI Thread Summary
Planetary systems can be influenced by electromagnetic (EM) forces, particularly through ionization processes occurring in stars and their stellar winds. While elements are typically electrically neutral, ionization can lead to charged particles, affecting nearby planets. The discussion raises the possibility of planets acquiring a net charge due to these phenomena, despite the overall charge balance in a planetary system being zero. The significant strength of the EM force compared to gravity suggests potential interactions that could influence planetary characteristics. Overall, the interaction between EM forces and planetary systems is complex and influenced by stellar activity.

Is there any star systems (planetary) that are influenced by the EM Force, hence as usual,sum of the charges of elements in the universe are electrically neutral.

That is a very strange question. As if a particular star system with planets out there might be affected by the EM force, while others are unaffected.

Elements (atoms) are not electrically neutral if they are ionized. There's a lot of ionization going on in stars (they're mostly plasma), in the stellar wind produced by stars, and in the planets that are impinged upon by the stellar wind from stars.

Bounded by space (vacuum), is there any chances a planet to be charged (either positive or negative) or discharge by any means? They say EM Force is 1040 times gravitation, I wonder in the realm of planets is there any possibility a celestial body would be charge by a phenomena?

Yes, but total sum of opposing charges on a planetary scale is zero.

Sure. Solar wind.

Why?
 
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 ...
