Protons are like little magnets, and little magnets are characterized by a single number, the magnetic moment μ. It's possible to measure the magnetic moment of the proton in the undergraduate lab with a modest circuit called a marginal oscillator. We will demonstrate a few of these circuits in action, and solicit advice on how to use varactors to modulate the frequency of oscillation of these circuits.
