Electromagnetism - Electrostatic Force: The Four Fundamental Forces of Physics #4a (2012x93)

Air date: Jun 26, 2012

Hank reaches the fourth and final of the four fundamental interactions in physics: electromagnetism. In this part, he teaches us about the electrostatic force, which builds up a charge in an object and can travel in the form of an electron stream. Stay tuned for Part II, where we will finish up the series with the magnetic force.
