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 In this example, there are three types of particles: one with positive charge, one with negative charge, and the third with no charge. An electric field is applied in horizontal direction pointing eastward. Periodic boundary conditions are applied in order to allow continuous flowing of the particles. The heat bath is also activated to prevent the charged particles from getting infinitely accelerated by the electric field. With this model, you can investigate, for example, the effect of temperature on the electric conductivity of an aqueous solution. return to top



	Central Concepts Key Concept: The model does exhibit continuous flow of charged particles, at a cost of simple dynamic motion. This model is being revised. Additional Related Concepts Physics/Chemistry Electromagnetic force Electron Ion return to top
