Detail Page

written by Andrew Duffy
This web page is an interactive physics problem on magnetic flux.  Given a bar sliding on rails with a current passing through it, the user is asked to determine if changes in the magnetic flux will cause the bar to speed up or slow down. The guide then works through the problem from both a magnetism and a conservation of energy perspective.  

This is part of a collection of similar simulation-based student activities.

Boston University Physics Applets: A Moving Bar:

Covers the Same Topic As Boston University Physics Applets: Changing Area in a Magnetic Field

This is a related simulation on changing magnetic flux.  It depicts a bar moving back and forth, representing the area of a loop.   The voltage graph on the right allows users to see how changing the area of the coil can induce an EMF.
