# PH 2021 - Physics II - ElectroMagnetism

3 lecture hours 2 lab hours 4 credits
Course Description
This course is the calculus-based continuation of PH 2011 . The purpose of this subject is to acquaint the students with the fundamental laws of electricity and magnetism. Particular topics include electrostatic vector fields, scalar potential, capacitance and dielectrics, energy and force in electrostatic systems, current, resistance and electromotive force, magnetic fields and forces and electromagnetic waves. PH 2021 is taught in an integrated lecture-lab format. (prereq: PH 2011  or PH 2011A ) (coreq: MA 137  or MA 137A )
