AI Thread Summary
The discussion centers on understanding specific electromagnetism formulas, particularly magnetic flux (Φ), magnetic flux density (B), permeability (μ), reluctance (Rc), and magnetomotive force (MMF). Participants express confusion about the derivation of these formulas and seek clarification on their references, noting that the equations are not presented in standard form. There is also a suggestion to use LaTeX for clearer presentation of the equations instead of unclear images. The conversation highlights the importance of clear communication in technical discussions. Overall, the need for better resources and clarity in formula presentation is emphasized.

I know what ##\Phi## and B are, I think they are the magnetic flux and its density. I think ##\mu## is the permeability. But I dont know what ##R_c## and MMF are and how are these formulas deduced.

Oh I see ##R_c## is the reluctance and MMF is magnetomotive force. I still dont know how these formulas are derived tho.
 
Which reference did you get these from ? They aren't in the usual standard form.

Since you seem to know how to use LaTeX, is there a reason you did not post those equations you are asking about using LaTeX instead of those fuzzy images?

oh it's others' hand script

Maybe so, but if you can read it, you can also enter it in LaTeX to benefit the rest of us.

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
