and for non-local jobs >_>
I'm graduating in May(the 11th to be exact), and was wondering about a couple of things. Say I see a tempting job opening somewhere that requires the BS, is it still ok for me to apply and note that I'm getting it PDQ? If not I kinda feel like I'm sitting on my...
Think I got it, I'll just put in my own work for shiggles
Well no, I don't know Latex worth a damn, suffice it to say I used the formula for B for a magnetic dipole sensed by another dipole, with the angle between them being pi/2, and ultimately I got
N=-I^2ua^2b^2/(4r^3) in the x-hat...
Just a thought here, buuuut isn't the B field of a circular current just a straight line going through its center(orientated with the right hand rule)? So...would there even be a torque on the square loop?
Edit: No wait that's totally wrong
Homework Statement
You've got a circular loop with a steady current I and radius 'a' a distance r from a square current carrying loop with sides of 'b' and current I, r >>> a or b(and they're arranged in such a way as you can think of the circular loop's dipole as pointing up, and the square...
Anyways, to actually answer the question, I think of an object with mass in a gravitational field and how it will travel "down" the gravitational potential. A difference in gravitational potential is easily visualizable as say...a hill!
in a similar fashion a positive electric charge in an...
The work done in moving a +ve charge from lower to higher potential is called Potential difference
Negati...er, no, un-affirmative
the work done is just that. But that's a little abstract a concept, so we normally look at the work done per unit time, which is the power. So if you use...

Ok, thanks for that, but I don't see how even knowing the first order perturbation energy gets you that expression for susceptibility
Not really a problem, I'm reading these 10 pages from a solid-state book for a professor, and it's a little over my head. Excuse the lack of LATEX but I copied it from another board I posted, and if you can help you likely know the equations involved anyways. I'm not expected to understand it...
A final, so I guess I'll never know :( senior level solid state class, 20 point question, I figure 10 for the explanation, and however many he feels like giving for getting to the voltage? I know, I obsess over how I did on a test after the fact, stressful habit
I had to explain the Hall Effect and derive the Hall coefficient
I didn't recall what the coeff. was but my explanation was solid and I was able to derive the Hall voltage, Vh=BI/net (t was thickness of plate, that's n and e, not the word net >_>)
I wrote that I didn't know what the...
Homework Statement
A square of edge a lies in the xy plane with the origin at its center. Find the value of the magnetic induction at any point on the z axis when a current I' circulates around the square.

Homework Statement
Two semi-infinite grounded plane conductors that intersect at the origin, with an angle of 60 degrees between them. A point charge of q is located some distance from the origin, and bisects the angle between the two conductors, where would the image charges be and what...
