Step Down Transformer (For Sonometer Experiment)
Product Code : SCL-PLE-11745
Quick Answer: The Step Down Transformer (For Sonometer Experiment) is a mains-isolated AC unit made to drive a sonometer electromagnet. It runs on 220–240 V AC, 50 Hz and gives a low-voltage AC output, so the electromagnet pulls on the wire at 100 Hz.

Key Features
- Dedicated driver for sonometer electromagnets.
- Low-voltage AC output locked to the mains frequency.
- Galvanic isolation from the mains and an internal fuse.
- 4 mm safety-shrouded sockets for the electromagnet leads.
Technical Specifications
| Specification | Value |
|---|---|
| Input | 220–240 V AC, 50 Hz |
| Output | Low-voltage AC |
| Magnetic pulse rate | 100 Hz on 50 Hz mains |

How It Is Used
The sonometer electromagnet is plugged into the 4 mm sockets and held close to the ferromagnetic wire. The alternating current makes the electromagnet attract the wire twice in every mains cycle, and the vibrating length is then adjusted with the bridges until the wire resonates, so its frequency can be compared with the laws of transverse vibrations.
