Here's a tip: You don't even need a sonometer. The frequncy of DC is zero.
The material of a sonometer wire is typically steel or a metal alloy with good elasticity and strength. These materials are chosen for their ability to vibrate easily and produce clear tones when tensioned and plucked.

A sonometer is an apparatus for investigating the vibration of a string or wire under tension. The equipment allows the length of the string and its tension to be varied. See Wikipedia entry 'sonometer' for more details

Tuning forks should be struck gently and put over sonometer boxes gently due to the fragile nature of the tuning fork and the sonometer box. The tuning fork is a metal rod with two prongs that vibrate at a specific frequency when struck. This vibration can be damaged or distorted if the tuning fork is struck too hard. Similarly, the sonometer box is a box filled with metal strings or wires, and if the tuning fork is placed too hard or too quickly, the metal strings can be damaged or distorted. Gently striking and placing the tuning fork over the sonometer box is also important for accurate results. If the tuning fork is struck too hard, the frequency of the resulting vibration will be higher than desired, and if the tuning fork is placed too hard or too quickly onto the sonometer box, the vibrations will be distorted and the resulting frequency will not be accurate. In conclusion, tuning forks should be struck and placed over sonometer boxes gently in order to protect the fragile nature of both the tuning fork and the sonometer box, as well as to ensure accurate results.
A horseshoe magnet is used in a sonometer to create a magnetic field that can interact with a vibrating metal strip (sonometer wire) to produce sound. When the magnet is placed near the wire and the wire is set into motion, the changing magnetic field induces an electrical current in the wire, which creates vibrations that produce sound waves.

The principle used in a sonometer is to study the vibrations of a stretched string. By adjusting the tension and length of the string, different frequencies can be produced and resonances can be observed. This helps in understanding the relationship between tension, length, and frequency of the vibrating string.
