Need a magnet and some iron filings? How about a compass? No worries because we got you covered with our Magnetic Fields Interative. Drag a compass needle through the space surrounding a bar magnet and observe the magnetic field created by the bar magnet.

Experiment with six bar magnets. Drag them about. Flip them around. Orient them as you please. Observe their attractions and repulsions. And observe how changes in position and orientation affect the magnetic field in the surrounding space.

What is needed to make an electromagnet? And what can increase the strength of the magnetic field created by an electromagnet? Explore these questions and more with our Electromagnet simulation.

It costs big $$$ to use one of these "Mass Spec" machines. But we'll give you time on ours free of charge. Tap this link and start firing ions down the chamber to see how much stuff they're made of. Take some time to analyze each section - the charge accelerator, the velocity selector, and the detector. We don't know if its worth a million $$$, but we do know it's worth your visit.
