Overview

The String Vibrator transforms mechanical wave demonstrations to hands-on activities that every lab group can easily perform. Featuring an elegant design with no motors or speakers, the String Vibrator allows students to study the fundamental characteristics of mechanical waves including wave speed, frequency, wavelength, amplitude, interference and resonance.

Typical Applications

  • Standing Wave Patterns
  • Mechanical Wave Characteristics

Features

  • Two recessed clamping surfaces allow it to be secured to a table with a C-clamp
  • Built in rod clamps allow for mounting vertically or horizontally on a standard lab rod
  • Tough custom plastic case to stand up to student use

Includes

  • String Vibrator Unit
  • Wave Cord (3 meters)
  • How It Works

    A neodymium magnet fastened to the stainless steel tongue is free to move within a coil. By supplying AC current to the coil, an alternating magnetic field is created which vibrates the magnet and tongue. Attached a string or elastic cord using the hole in the tongue and secure the other end to produce a waveform.

    The signal and power come from the included power supply, or, for a variable signal, use the Sine Wave Generator, 750 interface, or Xplorer GLX Power Amplifier.
