COURSE OUTLINE
ELECTRICITY AND MAGNETISM I
PHYS 201
Course description (3 credits):
This 3 credit course required of all Physics majors exposes students to the principles governing
electric and electrostatic phenomena. The areas to be covered are Electrostatics, Electric Fields
and Forces, Capacitors, and, Direct Current Circuits . Student activity will include but not be
limited to the attendance of lectures which will be multimedia based, where feasible;
participation in laboratory exercises; research; and, group discussions involving the theoretical
application of the laws governing electric and electrostatic phenomena.
Course Objectives:
The principal objective of this course is to equip the student with a firm foundation in the
principles of Advanced Level Electromagnetism. Upon successful completion of Phys 201
students will be able to
1. solve quantitative or qualitative problems requiring the use of verbal reasoning and/or
mathematical deduction of an analytical and/or graphical nature.
2. explain electric and electrostatic phenomena using the principles studied.
3. carry out laboratory experiments related to electric and electrostatic phenomena.
4. write reports resulting from laboratory experiments and research.
5. use knowledge of initial electric and electrostatic conditions to predict future conditions.
6. deduce mathematical expressions relating various electromagnetic quantities.
7. compare and contrast electric and gravitational field models.
8. successfully engage those portions of the CAPE and Cambridge examinations dedicated to
Electrostatics and Electricity.
