Research and Development using the THM1176
The The magnetic field is a three-dimensional vector quantity. A single Hall element only measures one component. A three-axis Hall instrument has... More Hall An instrument to measure magnetic flux density (B) or magnetic field intensity (H). More THM1176 finds many applications across the world, to map the five The cgs unit of magnetic flux density. Officially declared to be outdated, it is still popular for low fields. Equal... More line around an MRI, to map magnetic fields around a magnet or inside a magnet. It also serves as a reference for other magnetometers. At Metrolab, we are proud to enable these achievements.
