Criteria for selecting these multimedia examples from the list:
Topic that cannot be illustrated by conventional means – obviously 3D such as magnetic effects.
Ignored those that are intrinsically 2D phenomena – electrostatics, circuits and circuit components etc.
Ignored commercial adjuncts for textbooks.
Charge moving in a magnetic field and/or electric field (186/217/126)
Magnetic field inside a solenoid (138)
Multimedia selected from Proc. 11th European Workshop on Multimedia in Physics Teaching and Learning (MPTL XI) Szeged, Hungary, September 2006

The best multi-media may come from the least expected sources
Dedicated departmental server required in some cases as multimedia may be part of a large suite of applications
Many titles available on-line – BUT – few appear to be available for immediate download
internet access required in the lecture theatre
Applets cannot easily be imbedded into PowerPoint, use ‘LiveWeb’
http://skp.mvps.org/liveweb.htm
Need to distinguish between
sophisticated applets of interest to the lecturer (186 3D Lorentz force) for use as a teaching aid during lectures,
and simple illustrations that add little to a diagram but are suitable for private study by students (217 2D Lorentz force or 138 solenoid)

Applet accompanied by exercises seeking observations but there is no explanation of why the field changes as the number of turns increases or their spacing changes

Also need to check that the physics is correct!
