Directional magnetic field detector

magneticex03.in : Directional magnetic field detector

Requires: Device 3D/Magnetic 3D
Minimum Versions: Atlas 5.20.2.R

The example shows:

  • 3D structure formation using Atlas syntax
  • Model settings for 3D Magnetic field
  • Field detection using open circuited contacts

The Magnetic field in Atlas 3D is specified by setting some combination of BX,BY, or BZ on the MODELS statement. In this case the current flow is in the x-direction and so we set up a field in the y-direction and z-directions by setting BY and BZ on the models statement. Open circuited contacts are placed perpendicular to the y-direction and z-direction respectively. The potential drop in the y-direction (and hence BZ ) is measured between contacts Hall1 and Hall2 and that in the z-direction (and hence BY ) is measured between contacts Hall3 and Hall4. The ratio of potential differences generated can be seen to be in proportion to the ratio of magnetic field components, thus giving the direction of the field in the y-z plane.
