AI Thread Summary
Cesium gas atoms can be magnetized by aligning their spins in a magnetic field, and when the field is removed, the decay profile of the spins is influenced by relaxation and dephasing processes. The behavior is governed by two key time constants, T1 (longitudinal relaxation) and T2 (transverse relaxation). For a detailed understanding, resources on nuclear magnetic resonance (NMR) are recommended. Specific book suggestions were requested to aid in further study. Understanding these principles is crucial for exploring the demagnetization of cesium atoms.

Hello guys :),

if we magnetise Cs atoms with a magnetic field (or basically any other method like pumping), and got all the spins (moments) aligned in 1 direction, and then turn the cause of the alignment off, how will the decay profile look like? is it going to be a clean exponential decay? what are the equations governing this behavior?

I don't really know where to start with the answer to this.

I would appreciate an answer, reference, essay, article, book, or whatever kind of help you may provide me :-)

Thank you for any efforts :-)

You should probably try to find a book about NMR.
In the "classical" equations for this you end up with two time constants (T1 and T2) which govern the relaxation and the dephasing.
 
Thank you for your reply.

Could you please mention some specific book?

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
