also, im reading here that the first mag field causes all nuclei spin to align with the field (this is true)
but a second mag field at 90 degrees causes the nuclei to flip up if they havevnt done so. i thought the radio waves did that>

they didnt mention the raDIO WAves? som,ethings wrong here

no worries with just over 12 hrs left ia will say this:

the gyroscopic ration is 43.... the magnetic field strenght will determine the larmour freq.
so a field of 1.5 teslas gives a larmour freq of 43..*1.5 by varying the field at different locationsd we can actually define the location of each unit voxel :)

We don't need to know that much about them. You wont have time to write about that.

Just learn the fundamentals, and it's effect on society (both good and bad).
