TEL-21110 Oscillation Apparatus

For investigating and demonstrating harmonic as well as forced oscillations up to the resonance frequency. A freely oscillating spring and weight suspended in a plexiglass tube are made to oscillate via an externally attached, movable induction coil and function generator. A permanent magnet included with the TEL-21110 Oscillation Apparatus can be fastened to the lower end of the spring, thus allowing the free oscillations to be recorded via the induction coil using a recorder, digital storage oscilloscope or interface.
