Could someone please tell me if this paragraph is correct: Hydrogen atoms naturally spin about their axis. The spin produces a small magnetic field. When placed in a strong magnetic field, the protons align either with the magnetic field (low energy state) or against the magnetic field (high...

Thank you both. This is the first time I've studied MRI scans in depth and I have to prepare a presentation for tomorrow to present to my class. We're ~18 year olds so we don't know much about magnetic fields yet. If I was asked what precessing was, would I just say a rotation? I was...

I'm a little confused regarding MRI scans. So you add a strong magnetic field and the protons spin. However, some websites are saying the protons allign with or against the magnetic field. Other websites are saying the protons precess (not even sure what that is) and something about Larmor...
