Hi guys: I have a program which is supposed to fit x- and y-data to a certain function and give me the optimum parameters. This is no problem. What I want to do though is to perform a for loop that allows me to plot the CHANGE in those parameters over time (as I conduct a real life...

I have a heavy apparatus I am working on which needs to be mounted onto a plate (or some other support structure). The plate material has to be high strength, light-weight, and display very weak magnetic properties. Any suggestions for a material? Thank you.

I calculated the wire length based on the inner and out diameters, plugging them into an automatic formula I had.

Sorry, I haven't mentioned the details because I have been thinking of it as a conceptual problem. But here are the numbers: Tape thickness: 0.276 mm Tape width: 3 cm Outer diameter of coil: 43.5 cm Inner diameter of coil: 31.7 cm Coil separation distance (center to center): 33.3 cm Total...

Yes, I've measured the total resistance. Please see attached file for rough schematic representation of the coils. The lines indicate the connection between coils and the four aligned black segments are the coils as they would appear looking from the top down. So basically, current in...

The coils are a bit worn out and rusted...could that affect the resistance? Unless of course the material is not pure either, I don't know.

Yes but isn't the cross sectional area the width of the strip (if you're looking at a slice of it from the yz plane) multiplied by its thickness?

We'll I'm within the right factor of 10^-8 but my answer is about 2-3 times too high compared to the index value.

Thanks I am just calculating at room temperature. Based on the thickness and width (it's more like tape) and the length calculated: Resistivity=(resistance*thickness*width)/total length of both coils in connection

If I have a pair of coils connected in an anti-helmholtz configuration, with current flowing oppositely in both, and I wanted to calculate the resistivity- wouldn't the length of both coils just be summed up? I tried this but I am not getting the answer I want.

I am trying to calculate the magnetic field gradient for an anti-Helmholtz configuration. All the equations I have seen simply relate the strength of the gradient to some rudimentary variables (coil radius, separation distance of coils, etc.) but I am also interested in incorporating the...

Quick question: I keep seeing the following terms in my reading on nuclear magnetic resonance: - Spectral linewidth - Spectral bandwidth - Signal bandwidth Are these all qualitatively different terms? Or are they more or less referring to the same thing?

I have been invited for a second interview in the Netherlands for a PhD position composed of the following: (1)to present my masters thesis research and (2) an interview with a group of about 3 people. I'm sure someone has written about this before, but I wanted to know to what extent I...

Dear All, Do you know where I can find a cheap, above average-quality, purchase for a textbook on NMR called "Spin Dynamics: Basics of Nuclear Magnetic Resonance" by M. Levitt or "Quantum Description of High-Resolution NMR in Liquids" by M. Goldman. Thanks, Ahmed

I see what your'e saying, but the wording confuses me. For the question is "what is the probability that you end up in the final state." If we had been given a different problem with an initial wavefunction (for the infinite square well, for example) and instead we were asked "what is the...
