INTRODUCTION
This course starts
with the introduction of concepts related to
just electricity: charge, electric field, electric potential energy,
conservation of electric energy, etc. Notice that latter terms sound
already
very familiar to what you have learned in PH-211. Indeed, in PH-212 we
will use
those same concepts such as potential energy and conservation of
energy, which were
introduced in PH-211 when studying the gravitational force, the spring
force,
etc. You may also remember that for each (conservative) force we
associate a
corresponding potential energy. The nice surprise we have for you is
that the
only difference in PH-212 is that we will apply all those concepts to
the
particular case of the ELECTRICAL FORCE. So a great deal of your time
will be
devoted mainly to familiarize with the new terminology. The physics
background
is the same that you have already learned in PH-211.
In Part-1
of this summer
session we will apply the concepts of electricity to situations where
the
charges involved are at stationary positions; this is the reason for
the name
“Electrostatic”. In Part-2, we will
apply them to cases where the charges are in motion.
Charges in
motion
produce magnetism. This is very interesting! Just placing a charge in
motion
gives rise to magnetism. This means that electricity and magnetism are
manifestation of the same physical property: the electrical charge.
A very
curious student
will argue: wait a second, whether a charge is in motion or not is a
relative
concept. A guy in a particular system of
reference may see a charge at rest (he will see then only electrostatic
phenomena); for another guy in motion with respect to the first one
will see
the charge in motion (he will see electricity and magnetism phenomena).
How
could it be one guy see different phenomena than the other, just
because they
are moving relative to each other? Indeed, that is what happens! the
observers in
different system of reference will see different electromagnetic
phenomena.
This reveals another interesting phenomenon in physics: Electricity and
magnetism are relativistic concepts; their values depend on what system
of
reference you are using to measure them.
Since electricity and
magnetism are so intrinsically related, one
depending on the other, we call this course electromagnetism.
