Magnetostriction is a property of magnetic materials that causes them to change their shape or dimensions during the process of magnetization. The variation in materials' magnetization due to the applied magnetic field changes the magnetostrictive strain until reaching its saturation value. This effect is responsible for the humming sound you can hear coming from large transformers, which is caused by the magnetostrictive vibration of the transformer core.

Here are the steps to understand the magnetostriction effect:

1. Understand the Basic Concept: Magnetostriction is a phenomenon that occurs in ferromagnetic materials where the material changes its shape or dimensions in response to a magnetic field.

2. Know the Cause: The cause of this effect is the alignment of the magnetic domains in the material. When a magnetic field is applied, the domains align themselves with the field, causing the material to expand or contract.

3. Realize the Effects: This effect can cause a change in the physical dimensions of a material, which can be observed and measured. It can also cause the material to produce sound, known as magnetostrictive noise, when the magnetic field is changing.

4. Learn about the Applications: Magnetostriction is used in many applications, including sensors, actuators, and sonar systems. For example, in sonar systems, a magnetostrictive material can be used to convert electrical energy into mechanical energy, producing sound waves.

5. Understand the Limitations: The magnetostrictive effect is not very large in most materials. It is also not very efficient at converting energy, which can limit its use in some applications.
