Electricity and Magnetism

Magnetic Clouds

Visitors use magnets to "scoop" up iron particles contained in an oil-filled glass tube. Removing the magnets releases the iron into the oil, and the particles swirl in dense clouds. By once again moving the magnets close to the tube, visitors cause the clouds to organize into patterns revealing the magnetic field of the magnets.
