Product Code : SCL-M-11238
The Sonometer Excitation Electromagnet is a physics laboratory accessory used to produce periodic magnetic attraction near a suitable sonometer wire. It is intended for schools, colleges, universities and technical institutes conducting forced-vibration, resonance and alternating-current frequency experiments with a sonometer.
Product Description
The unit contains an electromagnetic coil and magnetic core arranged to create a changing magnetic field when connected to a suitable low-voltage AC source. When positioned close to a compatible ferromagnetic sonometer wire, the field applies a periodic force that excites transverse vibration in the stretched wire.
Students can adjust the vibrating length or wire tension until resonance produces a clearly observable increase in amplitude. The electromagnet is an accessory rather than a complete sonometer setup. It complements other physics miscellaneous products used for sound, wave and vibration experiments.
Key Features
- Electromagnetic excitation: Produces periodic magnetic force for driving a compatible sonometer wire.
- Resonance demonstration: Helps students identify the condition of maximum vibration amplitude.
- AC-frequency application: Supports the standard sonometer method for studying alternating-current frequency.
- Non-contact operation: Excites the wire magnetically without a mechanical striking mechanism.
- Laboratory connection format: Terminal or lead arrangement must be confirmed for the selected model.
- Reusable teaching accessory: Suitable for repeated supervised practical work when operated within its rated duty cycle.
- Specification-controlled supply: Coil rating, pole geometry, core construction and mounting details can be approved before ordering.

How to Use the Sonometer Excitation Electromagnet
- Set up the sonometer with the specified wire, bridges, hanger and masses.
- Place the electromagnet close to the middle of the vibrating wire without allowing contact.
- Connect the electromagnet to a switched-off, isolated low-voltage AC source.
- Verify the supply rating and all electrical connections.
- Switch on the supply and observe the wire vibration.
- Adjust the wire length or tension until maximum vibration indicates resonance.
- Record the resonating length, applied load and wire properties required by the experiment.
- Switch off the supply after each observation and before repositioning the electromagnet.
Safety note: Never connect the electromagnet directly to mains electricity. Use an isolated step-down source, avoid continuous energization beyond the rated duty cycle, and stop operation if the coil or leads become excessively warm.
Care & Maintenance
- Keep the coil, terminals and core dry and free from dust.
- Inspect leads and insulation before every experiment.
- Avoid dropping the unit or damaging the pole faces.
- Store it disconnected from the power source in a labelled equipment cabinet.

Frequently Asked Questions
What is a Sonometer Excitation Electromagnet used for?
It is used to apply periodic magnetic force to a suitable sonometer wire so that forced vibration and resonance can be observed.
Does the electromagnet include a complete sonometer?
No complete sonometer is confirmed. Treat the product as an excitation accessory unless the approved packing list states otherwise.
Can it be connected directly to mains electricity?
No. It should be connected only to an isolated low-voltage AC source matching the verified coil rating.
What type of wire is required?
The AC-frequency experiment commonly requires a wire that responds to the electromagnet. Confirm the wire material specified in the adopted laboratory procedure.
Why is the electromagnet placed near the middle of the wire?
The middle region is near an antinode for the fundamental mode, making the vibration easier to excite and observe during resonance.
Are connecting leads supplied?
Lead inclusion and connector type are not verified. Confirm the complete packing list before ordering.
Request the verified voltage, current, duty cycle and mounting details for the Sonometer Excitation Electromagnet, then review compatible laboratory meters for electrical monitoring during supervised experiments.
