Simulate magnetic resonance of a spin one-half particle with this tool. Magnetic Resonance of Spin One-Half Particles model simulates the magnetic resonance of a spin particle. Users can vary the frequency of an oscillating magnetic field and see how the quantum spin responds. Users can also vary the magnitude of both the oscillating field and a static field to observe how this affects the resonance.

The phenomenon of magnetic resonance is of practical importance, and the equations that describe magnetic resonance can be derived with relative ease. For this reason, the topic is appropriate for an undergraduate course in quantum mechanics, and it appears in some quantum mechanics textbooks. However, the equations cannot be solved analytically, so the treatment that is found in textbooks is relatively brief and involves confusing approximations. This simulation can hence provide a useful supplement for a course on quantum mechanics.

The phenomenon of magnetic resonance is interesting for several reasons. Measurements of magnetic resonance are used for practical applications that include the well known medical diagnostic tool "magnetic resonance imaging" (MRI) as well important tools for scientific research. These research tools can use either the magnetic moments of nuclei (known as "nuclear magnetic resonance" or NMR) or the magnetic moments of electrons. The latter goes by two names, "electron paramagnetic resonance" (EPR) or "electron spin resonance" (ESR).
