A high‐Q mechanical oscillator in the form of a metallic rod with an eddy current driver is described. With this oscillator and a simple crystal transducer the characteristics of a mechanical oscillator can be easily studied and Young’s modulus for the metal can be found. With an inexpensive FM transducer system the internal damping of the metal can also be measured.
