What is a disadvantage of using high-frequency alternating current in magnetic particle inspection?

Using high-frequency alternating current in magnetic particle inspection does have several implications regarding its effectiveness and equipment requirements. One significant disadvantage is that it requires more complex equipment. High-frequency systems necessitate the use of specialized power supplies and control mechanisms to maintain the appropriate frequency for effective magnetization. These components increase the complexity of the setup compared to standard equipment typically used for low-frequency magnetization.

Additionally, higher frequency currents can lead to a phenomenon known as skin effect, where the electric current tends to flow near the surface of conductors rather than throughout their volume. This necessitates careful consideration in the equipment design, which adds to the overall complexity. As a result, operators must be well-trained to ensure they are using this equipment correctly and effectively for the inspection process.

In contrast, the other options may reflect considerations regarding magnetic flux and inspection effectiveness for larger components but do not directly address the complexity of the equipment required for high-frequency alternating current systems.
