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 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
