Physics Playground

Every simulator in the course, gathered in one place. No reading required — just turn the knobs and play. Each tool also appears inside the lesson where its concept is taught.

Excite the magnetization and watch T1/T2 relaxation in 3D.

|Mxy| = 0.000 (signal)

Frame

Tip M into the transverse plane with a 90° pulse and watch |Mxy| (the detectable signal) decay with T2 while Mz recovers with T1. Drag to orbit.
