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.

What is magnetostriction for producing ultrasonics?
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.
What are the merits and demerits of physics?
Merits of physics include its ability to explain and predict natural phenomena, its impact on technological advancements, and its role in shaping our understanding of the universe. Demerits may include the complexity of its concepts, the need for advanced mathematical skills, and limitations in fully understanding certain phenomena such as quantum mechanics.
What are the merits and demerits of moving coil galvanometer?
The merits of a moving coil galvanometer include high sensitivity, accuracy, and ability to measure small currents. However, its demerits include limited range of measurements, susceptibility to external magnetic fields, and fragility of the moving parts.
What are the merits and demerits of research instrument?
Merits of research instruments include providing standardized data collection, enabling researchers to gather large amounts of data efficiently, and ensuring more accurate and reliable results. Demerits can include potential respondent bias, limitations in capturing nuanced or qualitative data, and the need for careful design and validation to ensure the instrument measures what it is intended to measure.
What is the name of the method of finding the volume of an object with an irregular shape?
The method of finding the volume of an object with an irregular shape is called displacement method or water displacement method. This method involves submerging the irregular object in water and measuring the volume of water displaced to determine the object's volume.
