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.
magneto striction oscillator is used to produce ultrasonic waves by using the the principle of inverse piezo electric effect
principle in magnetos striction
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...
yes because it posses the properties of ferro magnetic materials
its due to intermolecular collision of magnetic domain .nd its also due to magnetostriction ..
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
it is called the Coriolis effect
