Eddy Currents
Source Institutions
In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

Magnetic Shielding: Magnetic lines stop here
Source Institutions
Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

Magnetic Lines of Force
Source Institutions
With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

Circles of Magnetism IV
Source Institutions
In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.
