Electromagnetic Field Detectors are devices designed to measure the strength and direction of electromagnetic fields. These fields are produced by various sources, including electrical appliances, power lines, and wireless communication devices. The detectors can help identify areas with high electromagnetic radiation, which may be important for safety assessments or scientific research. These detectors typically use sensors to capture electromagnetic waves and convert them into readable data. Some common types include handheld meters and stationary monitoring systems. They are often used in fields such as environmental science, engineering, and health studies to ensure compliance with safety standards and to study the effects of electromagnetic exposure.
