Interactive - Magnetic Fields and Electromagnetism
Observe the interaction between a bar magnet and the needle of a compass with our Magnetic Field Simulator. And explore the inner workings of a Bainbridge mass spectrometer with our Mass Spectrometer simulation.
Activities
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.

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.
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.

Special thanks to Kirby!
