Product Information
Physics Laboratory Apparatus Electromagnet for Sonometer
An educational laboratory accessory for demonstrating magnetic interaction, wire vibration and resonance in sonometer experiments.
Designed for physics teaching environments where students explore vibrating strings and investigate AC frequency using a suitable experimental arrangement.
Product Overview
The Electromagnet for Sonometer is used in educational physics experiments involving the vibration of a stretched wire under magnetic influence. With a compatible power source and suitable wire arrangement, the apparatus helps demonstrate forced vibration and resonance.
It can form part of a practical setup for studying the frequency of AC using a sonometer, subject to the supplied model and experiment design.

Ordering note: Confirm operating voltage, transformer compatibility, mounting method and included accessories before placing an order.
Working Principle
When a compatible alternating current energises the electromagnet, its changing magnetic field interacts with a suitable sonometer wire. The resulting magnetic force can drive the wire into vibration. Adjusting the experimental conditions allows students to observe resonance and study the behaviour of a stretched wire.
f = (1 / 2L) √(T / μ)Fundamental frequency of a stretched string
L = vibrating length, T = tension, μ = mass per unit length. This relation describes the stretched-string model; it is not a product rating.
In a typical sonometer practical, resonance is observed by adjusting the vibrating length or tension. The exact procedure depends on whether the supplied setup uses an electromagnet with a magnetic wire or another compatible arrangement.
How the Experiment Is Performed
1Prepare the Setup
Arrange the sonometer and appropriate wire, then position the electromagnet as directed by the experiment manual.
2Connect the Supply
Use only a compatible, correctly rated supply or transformer. Check the product instructions and connections before energising the apparatus.
3Observe Resonance
Adjust the vibrating length or tension as required, observe the wire response and record readings for the assigned practical.
Safety: Do not connect the electromagnet directly to mains power unless the manufacturer explicitly specifies that connection. Use the approved supply and follow laboratory supervision and electrical safety procedures.
