I'm not quite sure what you meant .. So basically I have ω = γB1 = 2∏f1 formula, and if I write this in terms of period it would be like ω = γB1 = 2∏(1/t).. and I'm lost afterwards.. could you be kind to explain more in detail?

Hello If the time that takes for magnetization to rotate from its initial position (parallel with external magnetization) to x,y plane is given, how do we determine the value of B1? The formula I know: ω = γB1 = 2∏f1 lB1l < lBol angle between the magnetization and the external...

thank you so much for your help!

Thanks for explaining it for me. Just to clear things up, I want to confirm my understanding: 105 oscillations/sec. How many oscillations per 109 sec? (I got 109 by calculating Fd(t)=1/3). 105 oscillations : 1 second = x oscillations : 109 seconds x = 1.09 x 107 oscillations Then this...

I'm still lost.. The time elapsed was not given in the question, but how would you approach to calculate the number of oscillation from the period if the time was given? We are eventually calculating for Mxy(t)?

Homework Statement How many oscillations occur before Mxy decays to approximately 1/3 of its initial value, for a Larmor frequency of 100 MHz and T2 of 100ms?Homework Equations I was learning about how NMR works and about transverse relaxation. According to what I learned, we can express...
