The Magneto-Mechanical Harmonic Oscillator (MMHO) experiment examines the physics of the Simple Harmonic Oscillator at an introductory level, with special emphasis on high-Q oscillators and the physics of clocks. Since harmonic oscillators play such a central role in modern physics, and high-Q mechanical clocks (in the form of quartz crystal oscillators) are omnipresent in cell phones and other electronic devices, the MMHO experiment introduces students to a fascinating and vital area of physics and technology.
