Resonance,Resonance is the coordinated coupling of energy (stimulus) to matter (system), resulting in the smooth, rhythmic motion of matter according to its inherent oscillation dynamics.

Electromagnetic Fields,Magnetism and electricity are interrelated phenomena: a moving electrical charge creates a magnetic field. The reverse is also true: a magnetic field that varies in time induces the flow of electric current.

Macroscopic Magnetization,Each tissue is composed of innumerable magnetization vectors (μ) that are distributed in all possible orientations in space; thus, the net macroscopic magnetization vector (M) is zero (Fig. 3a).

Macroscopic Magnetization Revisited,The discussion in the preceding chapter is an approximation of the true state of affairs. We will now introduce the concept of rotation of the magnetization vectors.
