TEXT: GIANCOLI'S PHYSICS FOR SCIENTISTS AND ENGINEERS
Sherwood & Chabay's Electric and Magnetic
Interactions
TOPICS COVERED: Electricity , Magnetism, and Optics Giancoli,
chapters 22 thru 32
S&C Chapters 1-16, miscellaneous other
PURPOSE: Physics is the study of the properties of matter and energy. In Physics 213, our focus was particles. You learned how to describe and influence the motion of particles. You also learned about fundamental quantities and conservation principles. Now, we will build on your knowledge of physics. In this course, our focus will be fields. We'll study fields and their effects on particles by using a very well known and understood example -- the electro-magnetic field. During the first block, we will study the electric field and the work done by the field as it acts on an electric charge, while during the second block we will study the magnetic field. The third block, we'll study physical waves, and then tie all three blocks together by studying electromagnetic waves. In the third block, we will also look at the curious phenomena of interference and diffraction of light and we will have a brief introduction to modern physics. Along the way, we'll try to highlight the relevance and usefulness of the material to your future and every day living.
Electricity
Micro-electricity: Atomic level interaction of charged particles,
(mostly electrons), in electric fields.
Macro-electricity: Effects of micro-electricity, namely;
Coulombs Law:
Ohm's law: V = IR
Bio-Savart Law: dB = km (Ids x ) / r2
Faraday's Law: The emf (e) induced in a circuit is directly
proportional to the time rate of change of the magnetic flux thru the
circuit.
Lenz's Law: The polarity of the induced emf is such that it
tends to produce a current that will create a magnetic flux to oppose
the change in magnetic flux through the loop.
Electronics: Applications of Macro-electricity
Civilization is measured by the degree to which we control
energy.
Planting and harvesting is corraling energy from the sun.
Harnessing a horse is control and utilization of the horse's
energy.
Damming up rivers is harnessing gravitational potential energy.
Heat engines harness kinetic energy of gas molecules.
Batteries harness chemical energy, and are the first step in
controlling the energy of electrons.
As we climb higher on the technological ladder, it becomes more and
more apparent that each advance in technology depends on an increased
understanding and control of the behavior of electrons.
Mechnical forces are actually manifestations of the repulsive forces between electrons, as is also chemical interactions, and current flow in a conductor.
Light, (electro-magnetic waves, or photons) is created by the
acceleration of electrons.
Even gravity is somehow connected to the motion of electrons.
Scientists have found that the unfettered motion of electrons in
superconductors somehow affects gravity.
The progress of mankind will be determined by the degree to which
we learn to understand and control electrons.
This course is primarily the study of macro-electricity, which is
roughly equivalent to tying one end of a rope to a horse, the other
end to an object we want to move, and then trying to scare the horse
into running in the direction we wish the object to be moved, and
cutting the rope when the object has been moved far enough.
Micro-electricity would be equivalent to learning to speak horse and simply telling the horse what you'd like it to do.
Throughout we will try to blend in enough micro-electricity to hopefully ignite enough interest in you to inspire you to delve ever more deeply into this key to our technological future.

Discussion |
|
3-100 point tests |
Feb 2, Feb 23, March 16 |
No make up tests will be given. A missed test will be replaced by 1/2 of your final exam score. |
|
1-200 point Final Exam |
May 7, 2001 |
Final will be comprehensive. |
|
8 to 12 - 15 point experiments |
Varies, approximately one a week |
Lab write-ups due dates as indicated. Late labs cost 2 points each weekday late. You must make up missed labs to avoid an incomplete in the course. Make up labs will not be the same as regular class labs. |
|
1- 35 point Project or 7 5 point magazine article
reviews. |
Due Friday, April 27, 2001 |
Magazine article reviews must contain your name, class,
source, date and a brief synopsis of each article. |
|
FIELD TRIP Pensacola Naval Station, |
April 26, 2001 |
We leave from BS parking lot PROMPTLY AT 7:00(Attending a field trip can replace one lab, or be used for 20 bonus points). |
|
Miscellaneous hand-in problems and quizzes |
Due on date specified |
Priced as marked. |
- Bonus Points 40 pts. max.
- Letters to politicians, or editors expressing your opinion about issues regarding the physical universe in which we live. 1 point each, 15 points maximum. You may send copies of the same letter to a maximum of 5 different people. You may turn in letters in stamped, addressed envelopes, along with a copy for the instructor, on the same day project reports are due.
- Assisting math or physics students 5pts. per hour, 20 pts. max. (Must be done in the Library or Physics Lab verified in writing by either an instructor or librarian.)
- Occasional hand in bonus problems ( bonus questions on tests do
not count toward this max)5 pts. each, 30 pt. max.
- Book report, 10 pts. (Book must be approved by instructor prior to
reading, and reports are due on April 27)
GRADES:
The above total, excluding bonus points,will roughly be 700 points, (plus about 300 points, depending on miscellaneous assignments), and your accumulative total will be divided by the total to calculate your final average.
90 - 100 = A, 80 - 89 = B, 70 - 79 = C, 60 - 69 = D, 0 - 59 = F
NOTES:
l. Final percentage will be rounded UP, i.e., a final percent of
79.00000001 will be rounded up to 80.
2. You should keep all returned papers. You should also keep track of
the ratio (your accumulative total)/(The accumulative total possible
to date) as the quarter progresses. If this ratio is below 70 at
midterm (Mar. 2, 2001), you should come for a conference with the
instructor to discuss what each of us can do to retrieve you from
doom. Note: Unless otherwise specified, problems assigned this week
are due on monday of the next week. Experiments assigned this week
are due on Wednesday of the next week.
