Graduate Dipole moment of small circular antenna - only magnetic?
Okay, the more I am really looking at this, I realize that yes, the current is azimuthally symmetric. Sorry to answer my own question!- fhc6791

Graduate Dipole moment of small circular antenna - only magnetic?
When making an extension from linear dipole antennas to small circular antennas, I am only coming across expressions for a magnetic dipole moment (as opposed to having just an electric dipole moment for a linear dipole antenna). The expression being: m = πr2I at its peak The above expression...- fhc6791

Deep Inelastic Scattering, peak of cross section, width?
Hmm. You could treat the problem classically. There is quite a bit of material out there on Rutherford scattering by charged particles, the Symon textbook comes to mind. The electron's perihelion distance (if you consider it as an orbit with the target as a foci) should be the baryon's radius...- fhc6791

Undergrad Why doesn't Gaus's law count for charges outside the area?
It may help to think about this in terms of flux. Imagine you have a single positive charge inside a closed surface. Its field lines extend radially and pass through the surface, so the flux is related to the charge inside. Field lines of a charge outside the surface do not contribute to the...- fhc6791

Thanks for your reply. It's good to hear that others have been through this. Your first two sentences are spot on. I do have a great group that I work with, so I am lucky in that respect. And luckily, I'm not working. I just keep keep on truckin'.- fhc6791

Sleep-deprived graduate student
I am a new member to Physics Forums, actually I browse the site quite often, so I thought it was time I officially joined. I am a former high school AP/IB physics teacher, now a 2nd year physics graduate student finishing my classes and prepping for qualifiers. I'm currently taking Classical...- fhc6791
