How It Is Used
The electromagnet is set just below the steel sonometer wire and connected to an AC source. The alternating field pulls the wire periodically, forcing it to vibrate; moving the bridges until the wire resonates lets students study the laws of transverse vibration and find the frequency of the AC supply.
Frequently Asked Questions
How does the Electromagnet for Sonometer make the wire vibrate?
Alternating current in the coil magnetises the soft iron core periodically, so it attracts the metal wire in step with the supply and sets it vibrating.
