- How to derive the angle of which magnetic dipole in static magnetic field flips after short oscillating pulse (angle of nutation).

Hi, I am interested in derivation of flip angle in nuclear magnetic resonance. We have magnetic dipole in static magnetic field. The magnetic dipole is precessing around the vector of this field with Larmore frequency. After applying square magnetic pulse with amplitude B1 oscillating on frequency w similar to Larmore frequency (=resonance) with duration T, the vector of magnetic dipole moment flips by an angle γB1T. I am curious how to derive this formula for the flip angle.

Probably it is obvious, but I can not see it now and also was not able to google it somehow. I would be grateful for any suggestions of literature which contains this derivation, available online. Thank you.
