Four Fundamental Forces, Scale of the Universe, Cosmology and Astronomy
Fundamental interactions are the non-contact ways that elementary particles interact. Sal describes electromagnetism, strong interaction, and weak interaction as being mediated by the exchange of gauge bosons between particles.

Electromagnets - How Can Electricity Create a Magnet?
If you wrap wire around a screw and run an electric current through it, you create an electromagnet. What once had no magnetic pull is then able to pick up other metal materials. Marshall Brain demonstrates this for the camera in the...
