Electromagnet with Transformer for Sonometer Manufacturer,Supplier and Exporter in India

Electromagnet with Transformer for Sonometer (Product Code: SCL-292/044) is a sonometer accessory used to set a steel sonometer wire vibrating from the AC mains, so students can determine the frequency of the supply in the physics lab. Senior schools and colleges use it for the AC sonometer experiment, and it pairs the electromagnet with its own transformer in one item. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for sonometer work in Indian and overseas labs.

Key Details

What Is the Sonometer Electromagnet Used For?

In the AC sonometer experiment the electromagnet sits close to the steel wire between the two bridges, and the transformer feeds its coil from the AC mains. The alternating field pulls on the magnetic wire twice in every cycle, so the wire is driven at twice the mains frequency. Students move a bridge or change the load until a small paper rider on the wire is thrown off, which marks resonance, then calculate the wire's frequency from its vibrating length, tension and mass per unit length and halve it to get the supply frequency.

The method only works with a magnetic wire such as steel; brass or copper wire will not respond to the electromagnet. Keep the pole close to the wire without touching it, switch off at the mains before adjusting the set-up, and avoid leaving the coil energised between readings so it does not warm up unnecessarily.

What to Specify When Ordering

• Your mains supply voltage and frequency, so we can confirm the transformer suits it
• The sonometer it will be used with, for example a simple or 3-wire pattern
• Whether a sonometer, steel wire and slotted weights should be quoted with it

Frequently Asked Questions

What does the Electromagnet with Transformer for Sonometer do?
The Electromagnet with Transformer for Sonometer drives a steel sonometer wire into vibration using the AC mains. Students adjust the wire to resonance and use it to determine the frequency of the AC supply in the physics lab.

Why does the sonometer wire vibrate at twice the mains frequency?
With the Electromagnet with Transformer for Sonometer, the magnetic wire is attracted on both the positive and negative half of every AC cycle. It is therefore pulled twice per cycle, so the resonant frequency found is halved to give the mains frequency.

What supply does the Electromagnet with Transformer for Sonometer need?
The input rating of the Electromagnet with Transformer for Sonometer should be confirmed with us for the unit you are quoted. State your local mains voltage and frequency on the contact page so we can check it suits your lab.

Which wire works with the Electromagnet with Transformer for Sonometer?
The Electromagnet with Transformer for Sonometer needs a magnetic wire, such as steel, to act on. Brass, copper or other non-magnetic wires will not respond to the electromagnet, so use a steel wire on the sonometer for this experiment.

Is a sonometer included with the Electromagnet with Transformer for Sonometer?
The Electromagnet with Transformer for Sonometer is an accessory listed separately from the sonometer. If you need both, name the sonometer you want, simple or 3-wire pattern, on the same quotation request.

Who manufactures the Electromagnet with Transformer for Sonometer?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Electromagnet with Transformer for Sonometer (code SCL-292/044) as the OEM at its own factory in Saha, Ambala, Haryana, India, for buyers in India and international markets.
