String Vibrator

String Vibrator

WA-9857

 

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: Students learn about constructive and destructive interference by studying these waveforms
  • Mechanical Wave Characteristics: Wave speed, string density, frequency, amplitude and wavelength can all be examined

Includes

  • String Vibrator Unit
  • Constant Frequency Power Supply (60 Hz)
  • Wave Cord (3 meters)

Details

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

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.
