Lecture Engineering electromagnetics: Coulomb’s law and electric field intensity include all of the following content: Coulomb’s law, electric field intensity, field due to a continuous volume charge distribution, field of a line charge, field of a sheet charge, sketches of fields.
¾ With the modern knowledge about the structure of matter
we know that electric charges come from elementary
particles: negatively charged electron and positively charged
proton. In nuclei there are also neutron with no charge.
Interaction between charges: two positive charges or two
negative charges repel each other. A positive charge and a
negative charge attract each other. This interaction is called the
static electric interaction.
General physics 2: Electricity & Magnetism products about Electric Charge and Field (Electric Charges; Coulomb’s Law; Electric Fields; Electric Field of a Continuous Charge Distribution; Motion of Charged Particles in a Uniform Electric Field).

Most of the biochemical and biophysical processes of proteins take place
at membranes, and are thus under the influence of strong local electric
fields, which are likely to affect the structure as well as the reaction mecha-nism and dynamics.
Lecture Engineering electromagnetics - Energy and potential include all of the following content: Moving a point charge in an electric field, the line integral, potential difference and potential, the potential field of a point charge, the potential field of a system of charges, potential gradient, the dipole, energy density in the electrostatic field.
Its goals are to present basic concepts in a general setting, to show students how the principles of electrical engineering apply to specific problems in their own fields, and to enhance the overall learning process. Circuit analysis, digital systems, electronics, and electromechanics are covered.

This textbook is intended as an introduction to the physics of solar and stellar
coronae, emphasizing kinetic plasma processes. It is addressed to observational
astronomers, graduate students, and advanced undergraduates without a background
in plasma physics.
Coronal physics is today a vast field with many different aims and goals. Sorting
out the really important aspects of an observed phenomenon and using the
physics best suited for the case is a formidable problem.
The purpose of Power Electronics Handbook is to provide a
reference that is both concise and useful for engineering
students and practicing professionals. It is designed to cover
a wide range of topics that make up the field of power
electronics in a well-organized and highly informative
manner. The Handbook is a careful blend of both traditional
topics and new advancements. Special emphasis is placed on
practical applications, thus, this Handbook is not a theoretical
one, but an enlightening presentation of the usefulness of the
rapidly growing field of power electronics.
A vector is a quantity that possesses both magnitude and direction. Examples of vector quantities are displacement, velocity, acceleration, and force. A vector quantity can be represented by an arrow drawn to scale. The length of the arrow is proportional to the magnitude of the vector quantity. The direction of the arrow represents the direction of the vector quantity.physics in general is the most scientific study of "physical" and "interaction".
Electric motors convert electrical energy into mechanical energy by utilizing the
properties of electromagnetic energy conversion. The different types of motors
operate in different ways and have different methods of calculating the performance,
but all utilize some arrangement of magnetic fields. Understanding the concepts
of electromagnetics and the systems of units that are employed is essential to
understanding electric motor operation.The first part of this chapter covers the concepts
and units and shows how forces are developed.

The field of industrial electronics covers a plethora of problems that must be solved in industrial practice.
Electronic systems control many processes that begin with the control of relatively simple devices like
electric motors, through more complicated devices such as robots, to the control of entire fabrication
processes. An industrial electronics engineer deals with many physical phenomena as well as the sensors
that are used to measure them.
The generation, delivery, and utilization of electric power and energy remain among the most challenging
and exciting fields of electrical engineering. The astounding technological developments of our age are
highly dependent upon a safe, reliable, and economic supply of electric power. The objective of The
Electric Power Engineering Handbook is to provide a contemporary overview of this far-reaching field as
well as a useful guide and educational resource for its study.
Telecommunications is one of the fastest growing business sectors of modern
information technologies. A couple of decades ago, to have a basic understanding
of telecommunications, it was enough to know how the telephone
network operated. Today, the field of telecommunications encompasses a
vast variety of modern technologies and services. Some services, such as
the fixed telephone service in developed countries, have become mature,
and some have been exploding (e.g., cellular mobile communications and
The book consists of 21 chapters which present interesting applications implemented using the LabVIEW environment, belonging to several distinct fields such as engineering, fault diagnosis, medicine, remote access laboratory, internet communications, chemistry, physics, etc. The virtual instruments designed and implemented in LabVIEW provide the advantages of being more intuitive, of reducing the implementation time and of being portable.
