What are the methods for producing Ultrasonic waves?
Ultrasonic Production:
Three methods there for producing Ultrasonic waves are as given below:
a. Mechanical generator or Galton’s whistle.
b. Magnetostriction generator.
c. Piezo-electric generator.
In this section, know the method of producing ultrasonic waves by using Magnetostriction method.
The physical value which does not depend on any other physical quantity is known as a fundamental physical quantity like length; mass and time are known as fundamental units.

A mild steel ring has a radius of 50mm and a cross-sectional area of 400mm 2 . A current of 0.5 A flows in a coil wound uniformly around the ring and the flux formed is 0.1mWb
Permittivity of free space; electric constant; epsilon_0 The ratio of the electric displacement to the intensity of the electric field generating it in vacuum. This is equal to
