Electromagnetic Fields, Forces, and Motion

Readings

Texts

The readings in the table below are separated into textbook sections and video demonstrations. The textbook sections come from the Zahn and Woodson/Melcher textbooks. The video demonstrations accompany the Haus/Melcher textbook. The Haus/Melcher textbook is used as a supplement for the first half of the course in addition to the textbook sections listed below. All three textbooks can be found here.
