Electromagnetism: The branch of physics concerned with the interaction of electric currents or fields and magnetic fields. Fiber Optic Sensor: A sensing device that uses light guided through fibers to detect changes in a parameter, such as temperature or pressure. Electrical Interference: Disturbances generated by external sources that affect an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. Ultrasonic Sensors: Devices that measure the distance to an object through the emission of ultrasonic sound waves and the detection of their reflections, used in various applications like level sensing and obstacle detection.
