In relation to line locators, what does inductive mean?

Inductive refers to the method by which line locators recognize the presence of a buried utility without needing to make a direct electrical connection to the line. In this context, an indirect connection through radio waves means that the locator uses electromagnetic fields generated by the transmitter to induce a signal in the buried line. This method allows the line locator to detect the utility's location through passive means, which is particularly useful for lines that are not easily accessible or where making a direct connection is not practical or safe. Inductive coupling is essential for many line location applications, as it enables safe and effective detection of buried utilities by capturing the emitted electromagnetic signals.
