A Gauss meter is a device used to measure the strength of magnetic fields. It quantifies the magnetic flux density, typically in units called Gauss or Tesla. These measurements are essential in various fields, including physics, engineering, and medical applications, such as MRI technology. Gauss meters come in different types, including handheld and digital models. They often feature a probe that detects magnetic fields and displays the readings on a screen. This tool is valuable for assessing electromagnetic interference, ensuring safety in workplaces, and conducting scientific research related to magnetism.
