Course Description:
Electrostatics and magnetostatics. Solution of Poisson's and Laplace's equations. The Lorenz equation and force. Time varying fields. Magnetic circuits and transformers. DC and AC motors.
Precludes additional credit for ELEC 2601 or ELEC 3504.
Prerequisites: MATH 2004 and (PHYS 1004 or PHYS 1002).
Lectures three hours a week, laboratory and problem analysis three hours alternate weeks.
Course Marking Scheme:
- 50% Final Exam (During normal exam period)
- 15% Test #1 (February 15, 2012)
- 10% Test #2 (March 16,2012)
- 25% Laboratories (5% each)
Notes: The final exam is for evaluation purposes only, and will not be returned to the student.
Class Hours:
Wednesdays and Fridays, 4:05am until 5:25pm
Class Location:
Room 240 Tory Building.
Lab/PA Hours and Location:
Labs and PA sessions will be held according to the schedule on the calendar page of this blog (link tab is at the top of the page). Labs are always in 4275ME. Monday PA sessions are in 411SA. Other PA sessions are in 4124ME.
Laboratory Policies:
Labs will alternate with PA sessions. Lab reports are due at the designated time and date (as designated by the TA; generally at the end of the lab session). Late labs are worth 0. In order to pass ELEC 3105, it is necessary to complete all five labs. If you miss a lab due to illness you must arrange a time to complete a make-up lab. The format of the lab write-ups will be discussed as needed at each lab session. You don’t need a hardcover lab book.
Test Policy:
The following will be accepted as reasons for missing a test:
- crisis in family
- illness (with doctor’s note)
In the event that a test is missed for either reason, the value of the test will be added to the value of the final exam in order to calculate the final grade. There will be no make-up tests.
Course Topics:
Suggested knowledge for this course: Vector operations, vector calculus, basic physics. The following topics will be covered during the course lectures, approximately following the schedule shown below.

Week 7: Magnetic Fields in Matter
Magnetic dipoles; Diamagnetic, paramagnetic and ferromagnetic materials; Magnetic circuits.
Weeks 8: Faraday's Law
Faraday’s law and induced EMF; Lenz's law; Eddy currents; Inductors.
Week 9: Transformers
Flux coupling and the ideal transformer; Impedance transformation; Losses in real transformers
Week 10: DC Motors and Generators

Week 12: Review
Textbooks:
M. Sadiku, Elements of Electromagnetics, 5th edition, ISBN 978-0-19538775
Optional:
J. Edminister, Schaum's Outlines Electromagnetics, 3rd edition, ISBN 978-0-07-163235-5 (Note that the notation in this book is different than that found in the Sadiku book. This may confuse some students. The book is good if you want to have extra practice problems.)
