Quick Answer: The Electromagnet for Sonometer is a physics accessory that excites a stretched sonometer wire for vibration, resonance and frequency experiments when connected to a suitable power source or signal input.
Last updated: October 2026
Key Features
Sonometer accessory for vibrating string experiments.
Gives repeatable excitation without plucking the wire by hand each time.
Supports resonance, frequency and sound wave demonstrations.
Used to study the laws of stretched strings.
Works with a compatible sonometer and a suitable electrical input source.
About This Product
The electromagnet is placed close to the sonometer wire without touching it and connected to a compatible power supply or signal source. After setting the wire length, bridge position and tension, students switch on the input, watch the wire vibrate and change the length or tension to find resonance. The readings relate frequency to string length, tension and mass per unit length.
Frequently Asked Questions
Q1. Does the electromagnet touch the sonometer wire? No. It is positioned close to the wire without touching it. When the electrical input is switched on, the wire vibrates and resonance can be found by adjusting length or tension.
