While more complex circuits have been used, most biological or chemical investigations do not require them as long as the required power and proper measuring devices are available. The frequency of oscillation of the simple electron tube oscillator pictured is determined by the relationship/ = l/[27r(LC)'^'] where L is the inductance of the coil shown with the magnetostrictive tube present and C is the capacitance. By var3dng C the frequency of the oscillator can be adjusted to the natural period of the rod, at which point the largest amplitude of vibration will be produced. Li is the coil necessary to produce the proper static operating field for the.
