Magnetostriction Coefficient Measuring System

Magnetostriction refers to the changes in linearity and volume caused by changes in the magnetization state of ferromagnetic substances.

Magnetostriction is a property of ferromagnetic substances, which can be used to convert magnetic energy into mechanical energy. It is used for ultrasonic generators, actuators and sensors.

Magnetostriction is a phenomenon that can only be exhibited in magnetic materials such as iron, nickel, cobalt and their alloys.

The principle of magnetostriction is based on the fact that these materials have a certain magnetic properties. Magnetic materials placed in a magnetic field undergo microscopic deformations in their molecular structure, changing their dimensions.

Sample Requirements

The overall method measures magnetostriction, requiring a diameter of 15 - 45 mm and a height of 40 - 55 mm. The more parallel the two ends, the better, and the parallelism is less than 0.05 (the flatter the better). The pressure is not greater than 15 MPa.
The strain gauge method is used to measure magnetostriction. When no pressure is applied, the flat area of the sample surface should have an area of at least 5 × 10 mm. The flatter the end face of the sample under pressure, the better, and the thicker the better.
The magnetic field strength does not exceed 8000 Oersted by default.

Application

Measure the magnetostriction coefficient of positive and negative magnetostrictive materials, ferrite, soft magnetic, ferromagnetic and other materials
