This Activity Requires:

  • Java 1.5+ - Java 1.5+ is available for Windows, Linux, and Mac OS X 10.4 and greater. If you are using Mac OS X 10.3, you can download MW Version 1.3 and explore within it instead.

      Test your system to see if it meets the requirements

Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

With the model, you can observe that in some circumstances, particles with a dipole moment may self-align in a common direction, which may change with respect to time. In other circumstances, particles may form a few domains within which their dipole moments point to a common direction. Particles with a dipole moment will yield to an applied electric field, which results in an alignment of their axes to the direction of the applied field.
