Definitely the economy is changing. It is difficult to predict for now how things will change. But in general industry is more tied to...

For some background, I'm currently a 3rd year physics major with an astro specialization studying in Canada, and as undergraduates are...

Thank you, I think I got it. If I have any vector field ##\vec v=\vec v(x,y,z)##, then in general the componentes would be ##v_x...

Yes, in the general case ##\mathbf{A} = \mathbf{A}(x,y,z,t)## is some vector field that depends on position (and time), and you'll need...

The radiation resistance is supposed to be very small and does not change the logic in a fundamental way. The time constant (TC) does...

Thanks Dale for the info. So, this resistance would be a factor in the ramp up of voltage to V. If the ramp up is done very slowly, then...

Thanks for making my point! Yes, “hours” is not forever! However, the analysis says times required are likely to be much longer than...

Agreed. You could design circuits with a superconducting component and a long time constant and you could design circuits with a...

What analysis? All I have seen is your unfounded assertions to that effect. Indeed. Please do.

The physical arrangement of the circuit components will be important. You have not described the complete circuit. Depending on the...

You keep pointing to contrary "observations". To support that claim, please cite a scholarly reference that exhibits what is observed...

Ramping up a MRI magnet is almost linear, it takes a few hours which is not almost forever, and I don’t see what you think is contrary...

This depends on the geometry but is typically in the range of 50 to 300 ohms.

Hmmm. What makes you think that? Do you have a reference that shows an experiment where it doesn’t match?

The series R+L will need a return circuit, that has not yet been defined. In effect, R1+L1 is a transmission line operating against an...
