Magnetic field meters are devices used to measure the strength and direction of magnetic fields. They are commonly employed in various fields, including electronics, environmental studies, and safety assessments. These meters can detect both static and dynamic magnetic fields, providing valuable data for research and industrial applications. Typically, magnetic field meters use sensors like Hall effect sensors or fluxgate magnetometers to capture magnetic field intensity. The readings are often displayed in units such as teslas (T) or gauss (G). These instruments help ensure compliance with safety standards and are essential for understanding the effects of magnetic fields on both technology and living organisms.
