An AC/DC magnetic meter, also known as a gaussmeter or magnetometer, is a device used to measure the strength and direction of magnetic fields. These meters can detect both alternating current (AC) and direct current (DC) magnetic fields, making them versatile tools for various applications. They are commonly used in industries such as electronics, automotive, aerospace, and research laboratories to measure magnetic fields generated by magnets, electric currents, machinery, and other sources. The measurements taken by an AC/DC magnetic meter are typically expressed in units such as gauss or tesla, which quantify the intensity of the magnetic field.
