Course Description: This course deals with Electromagnetism which introduce to the students
electromagnetic fields and forces. Topics include Coulomb’s Law, electric fields, Gauss’ Law, Electric
potential capacitance, circuits, magnetic forces and fields, Ampere’s Law

point charges.
• Understand the Law of Conservation of Electrical Charge and its
applications.
• Understand the concepts of Capacitors and Resistors and their properties.
• Perform calculations to determine the equivalent Capacitance and the
equivalent Resistance in an electric circuit.
•
Perform calculations to determine the currents and voltages in an electric
circuit using the Kirchhoff’s Laws.
• Calculate the charge of a Capacitor in a RC circuit at any time and its
applications in electronic devices and medicine.
• Understand the concepts of superficial currents, Magnetic fields and
Magnetic forces, and its applications in electric motors, electric generators
and electro-magneto.
The major objectives of this course are for students to learn the fundamental
Course Objectives:
principles of electromagnetism, to continue to develop solid and systematic problem solving skills, and to
lay the foundation for further studying in physics, physical science, and engineering. Although this class
will branch into new material, it is considered a continuation of the Physics I and Physics II courses taught
at Proyecto Science.
•
Electrical Charges: The students will be given a brief history of the discovery of electrical
charges and will be introduced to the idea of point charges. Discussion will include atomic and
sub-atomic particles (protons, neutrons, electrons, positrons, quarks, radioactive decay: alpha
particles, beta particles, gamma radiation, etc), the Law of Conservation of Charge, Properties of
Electric Charge, Types of Materials (Conductors, Insulators, Semi-conductors) and Methods of
charging (by conduction and by induction).The students will do calculations of the force between
two or more point charges using the Coulomb’s Law and how the different environments can
affect the electrical force. An introduction of the force between a point charge and a charged
object using Calculus will be discussed. The Electric Field and field lines will be introduced and
explained.
•
Electricity: The idea of electrical current will be discussed. The students will be introduced to
the idea of free electrons in conductors and how charge is transported through the different
materials. The students will learn how the generator of Van De Graff works and then they will
realize how lightings are produced in a storm.
•
Capacitance and Resistance: The students will be introduced to the electric circuits. Voltage will
be discussed along with the electromotive force and internal resistance in batteries. Capacitors
and Resistors will be introduced along with the standard formulas for calculating the equivalent
capacitance and the equivalent resistance in an electric circuit. Properties of the Dielectrics will
be discussed. Kirchhoff’s Laws will be introduced to calculate currents and voltages through the
different paths in an electric circuit. The Law of conservation of charge will be applied in electric
circuits and will explain how charge is conserved through the circuit. Students will need a
background in solving linear equations by substitution, linear combination, Cramer’s rule and/or
using an inverse matrix.
•
RC Circuits: Students will be introduced to the Resistor-Capacitor circuit and they will be able to
find the charge at any time. Calculations will be done using equations for the circuit when is
charging and when is discharging. Students will analyze the graph of charging and discharging
the circuit and the properties of the capacitors.
•
Electromagnetism: Students will discuss the properties of the magnetic fields and the magnetic
forces. An explanation of the superficial currents in certain type of material (magneto) will be
exposed. Motion of a charged particle in a Uniform magnetic field and its applications will be
discussed. Students will be able to understand and explain how an electric motor, an electric
generator and an electro-magneto work.
