The transverse component mxy decays to 37% of its initial. The decay of transverse magnetization is also a relaxation process, which can be characterized by specific relaxation times, or t2 values. T2 relaxation is the process by which the transverse components of magnetization (m xy) decay or dephase

More generally, after excitation by 90 degree pulse, the magnetization will return to equilibrium by a combination of t1 and t2 relaxation
This is called a free indunction decay (fid)
Longitudinal and transverse magnetization components in thin films The transverse magnetization component generates a free induction decay (fid) nuclear magnetic resonance signal in the receiver coil, which shows rapid decay defined by t 2 ⇤ (thick line). Ransverse component of the net magnetization vector induces a current in the receiver coil For the induction of current, the nuclei must be spinning in the nuclei gradually spin out of phase, the signal induced in the coil
Transverse magnetization is an unstable, or excited, condition and quickly decays after the termination of the excitation pulse
