This is higher-level than electromagnetism, but maybe still relevant  
(and fun to play with anyway):

In Etoys, go to "Gallery of Projects", then "ComputerLogicGame" (3rd  
item in 3rd row I think). This is simulating wired logic gates in a  
very simple manner, representing the on/off state by a color. E.g. the  
yellow rectangle is "on", while the piece of wire is "off":

Moving the wire's red dot over the source switches it on, too:

As you can see this does not require a closed circuit so it is not a  
simulation at the electrical level.

The example shows an inverter's (Not gate) script, and this is  
actually the only code for this object:

If the kids had prior experience with Etoys they could build this on  
their own from scratch pretty easily.
