Electric and Magnetic Fields (see "Important Notice!")

Interactive, scaffolded model

Launch Activity

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.

	Important Notice! Due to a recent change in Quicktime, this activity will only work for computers using Quicktime version 6. We are working on fixing this problem, but it will take some time. Thank you for your patience. return to top



	Overview and Learning Objectives Charged particles experience a force when in an electric field and, if moving, in a magnetic field. Magnets experience a force in magnetic fields, and, if moving, in an electric field. In this activity students experiment with both types of fields and compare representations of fields in 2D. Students will be able to: determine how a charge particle orients itself in a magnetic field; describe a 2D representation of a 3D field; experiment with initial velocity and charge to separate particles in a mass spectrometer. return to top

	Benchmarks and Standards AAAS THE PHYSICAL SETTING: FORCES OF NATURE - Different kinds of materials respond differently to electric forces (Full Text of Standard) THE PHYSICAL SETTING: FORCES OF NATURE - Magnetic forces are very closely related to electric forces and can be thought of as different aspects of a single electromagnetic force (Full Text of Standard) THE PHYSICAL SETTING: MOTION - Accelerating electric charges produce electromagnetic waves around them (Full Text of Standard) NSES Physical-Science: Energy Conservation / Entropy - 2 All energy can be considered to be either kinetic energy, which is the energy of motion; potential energy, which depends on relative position; or energy contained by a field, such as electromagnetic wave (Full Text of Standard) return to top
