Each time a flow of electricity is passed through the coil of wire surrounding magnetostrictive material, a magnetic field is formed. The property that the magnetostrictive material has under the influence of this magnetic field can be referred to as free strain.

Materials such as nickel, cobalt, iron and their alloys have the ability to contract and expand when they are placed into a magnetic field. This is a property known as magnetostriction. Prior to these materials being magnetized, they have magnetic domains within them, which are distributed in a random or disorganized manner. In order for these domains to become organized, or arranged in a parallel configuration, they should be placed under a magnetic field. A magnetostrictive transducer is made up of many plates that are magnetostrictive, arranged parallel to each other.

With the latest transducer technology, a coil of wire is placed around the magnetostrictive materials. The coil in this case is often referred to as a drive coil. This is simply done by winding the wire around the length of the material, from one pole to another. The purpose of these transducers ...
... is to change and utilize the energy that exists in a magnetic field. The end product in this case should be mechanical energy, which can be used in devices such as generators. This conversion of energy is made possible due to the property of magnetostrictive materials going through magnetostriction.

Each time a flow of electricity is passed through the coil of wire surrounding magnetostrictive material, a magnetic field is formed. The property that the magnetostrictive material has under the influence of this magnetic field can be referred to as free strain. The effect that this field has on the magnetostrictive material is to cause it to either contract or become longer. This creates a sound wave, which passes through the solid material, causing it to vibrate. The way it passes through the solid is similar to a fluid state. This wave is referred to as ultrasonic.

The process of magnetostriction can be influenced by the stress in the material that is magnetostrictive. In order to obtain the maximum level of magnetostriction, the material can be pre-stressed. There are several benefits that a magnetostrictive transducer has over other options, such as a piezoelectric transducer. This type of transducer changes electrical energy into mechanical energy. One advantage of the transducer is the fact that it can be used to convert a number of materials. There are fewer limitations such as size, due to the fact that this method is suitable for materials with a larger volume. These may include long tubes and pipes.

Another advantage of using transducers is the longevity effect they present. Materials that go through this process often have a longer lifetime. The time taken to carry out the process should also be considered. The time taken for the transducer to carry out tests is relatively short. There are some systems that require one to apply a lot of amplitude and power. In this case, piezoelectric magnetostrictive transducers are not the best option. This is because transducers that are magnetostrictive provide an option that is more effective and safer, especially in the event that high temperatures are used. For this reason, transducers are widely used to perform tasks such as the removal of scales in solid pipes.
