magneto striction oscillator is used to produce ultrasonic waves by using the the principle of inverse piezo electric effect
This is an effect where by materials change their shapes (or dimensions) when exposed to magnetic field or vice versa. These materials are smart materials that can be used for energy conversion and harvesting applications and for developing sensors and actuators.
principle in magnetos striction
Yes, copper can be used as a rod in a magnetostriction generator. Copper is a good conductor of electricity and can help facilitate the generation of electrical energy in the system. However, the specific design and material requirements of the magnetostriction generator should be taken into consideration when selecting the materials for the rod.
Some demerits of the magnetostriction method include its lower sensitivity compared to other non-destructive testing methods such as eddy current testing, its dependency on the material's magnetic properties, and its limitation in detecting surface defects accurately. Additionally, magnetostriction testing can be influenced by external magnetic fields and may require a skilled operator to interpret the results accurately.
Magnetostriction generator is used to produce ultrasonic waves. It consist of a ferromagnetic rod and an electronic oscillator.when alternating current is produced by the electronic oscillator the rod experience a small change in length with the production of ultrasonic waves...

An oscillator whose frequency is controlled by a magnetostrictive element.Magnetostriction is a property of ferromagnetic materials that causes them to change their shape when subjected to a magnetic field. http://en.wikipedia.org/wiki/Magnetostriction ~MECHASUN~
a ferromagnetic rod like iron or nickel when placed in alternating magnetic field, the rod vibrates longitudinally and produce ultrasonic at resonance condition
Magnetostriction is a property of certain materials that causes them to change shape when exposed to a magnetic field. This mechanical deformation can be used in magnetostrictive transducers to generate ultrasonic waves by converting electrical energy into mechanical vibrations. As the material expands and contracts due to the alternating magnetic field, it creates ultrasonic waves that can be used for various applications such as ultrasonic cleaning or medical imaging.
