The string wire of the sonometer is a non-magnetic metallic wire like brass or copper. A horse shoe magnet is placed at the middle of the sonometer wire so that the magnetic field is applied perpendicular to the sonometer wire in a horizontal plane.
.
Similarly one may ask, why steel wire is used in Sonometer?
We use a non -magnetic i.e like copper wire in the sonometer so that it doesn't get affected by a permanent shoe-magnet. But if we use an iron or steel wire, it will be attracted by horse-shoe magnet and will not be able to vibrate under the action of electric current and magnetic field.
what is the use of Sonometer? A sonometer is a diagnostic instrument used to measure the tension, frequency or density of vibrations. They are used in medical settings to test both hearing and bone density.
Also question is, what is the Sonometer?
A Sonometer is a device for demonstrating the relationship between the frequency of the sound produced by a plucked string, and the tension, length and mass per unit length of the string. These relationships are usually called Mersenne's laws after Marin Mersenne (1588-1648), who investigated and codified them.
Why it is called Sonometer?
Originally Answered: Why sonometer is called sonometer ? sonometer is derived from 2 words - (sono+meter) ; where sono stands for sound. Thus sonometer is an instrument which measure frequency of sound wave. Sonometer is a very simple method for the determination of Frequency of a.c. mains.

But if we use an iron or steel wire, it will be attracted by horse-shoe magnet and will not be able to vibrate under the action of electric current and magnetic field.What is a Sonometer wire?
The string wire of the sonometer is a non-magnetic metallic wire like brass or copper. Then the resonance takes place and the wire vibrates with maximum amplitude. At this stage, the length of the wire segment is called the resonating length and it increases with increase in the mass of the suspended weights.What is the principle of Sonometer?
Basically a sonometer is a device based on the principle of Resonance. It is used to verify the laws of vibration of stretched string and also to determine the frequency of a tuning fork. "When the frequency of the applied force is equal to the natural frequency of the body, the body vibrates with very large amplitude.What is ac frequency?
Alternating current (ac) frequency is the number of cycles per second in an ac sine wave. Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second.Why external magnetic field is used in Sonometer?
A horse shoe magnet is placed at the middle of the sonometer wire so that the magnetic field is applied perpendicular to the sonometer wire in a horizontal plane. When the length 'l' of the sonometer wire vibrates with maximum amplitude, the frequency of the applied A.C. is equal to the natural frequency of the wire.Why horseshoe magnet is used in Sonometer experiment?
What is the purpose of a u-shaped magnet on a sonometer? Because the conductor in a magnetic field experiences force F=IxB, without the magnetic field created by the magnet, there would be no force.Why is Sonometer box hollow?
The holes in the sonometer box provides a way so that vibrations from the tuning fork (which is excited near the sonometer) is transferred to the inside of the sonometer box. Hence holes are provided to the sonometer box to communicate the frequency of vibration of the string to the inside hollow portion of the box.Which type of waves are produced in Sonometer experiment?
Waves produced in a sonometer are crests and troughs produced in a string. Hence they are transverse waves.How long is a Sonometer?
Sonometer consists of a hollow rectangular wooden box of more than one meter length, with a hook at one end and a pulley at the other end. One end of a string is fixed at the hook and the other end passes over the pulley.What are the requirements of a Sonometer?
Materials Required- A sonometer.
- A set of tuning forks of known frequency.
- 0.5kg weight hanger.
- Some 0.5kg slotted weights.
- Rubber pad.
- Paper rider.
