A detailed explanation of the overview of coils used as sensors and their application examples!
Coils are common components used in many electronic devices and electrical products, but they can also be utilized as sensors. This article provides an overview of how coils are used as sensors and details their applications. A coil is an electronic component shaped like a wire wound in a spiral. Generally, the wire is wound around a core made of iron or a magnetic material. By passing current through the coil, it can generate a magnetic field, and various applications can be realized by utilizing this characteristic. *For more detailed information, please refer to the related links.
