By dropping a magnet through a copper tube, participants learn how the magnetics fields can still interact with nonmagnetic materials.
Participants learn the everyday science of electric motors in this fun and engaging workshop activity.
Off-Grid Phone Charger
Constructing this simple and inexpensive portable cellphone charger provides an introduction to soldering and electronics.
Practically, these units can be used for charging in regions of the world where grid electricity is not readily available.
This demonstration provides a three-dimensional visualization of magnetic field lines using ferrofluid.
