A Gauss meter is a device used to measure the strength and direction of magnetic fields. It quantifies the magnetic flux density, typically in units called Gauss or Tesla. These meters are commonly used in various fields, including physics, engineering, and environmental studies, to assess magnetic field levels in different environments. Gauss meters can be handheld or stationary, and they often feature digital displays for easy reading. They are essential tools for researchers and technicians who need to monitor magnetic fields in applications such as MRI machines, electromagnetic compatibility testing, and magnetic material characterization.
