Magnetic Field:
Our first experience with magnetic field is with
magnet bars. Our observation shows that two magnet
bar could repel or attract each other depending to
their relative orientation.
Each magnet has two poles north pole our south pole.

Electromagnetic Induction:
As Oersted experiment showed, electric current can produce
magnetic field. Faraday an English physicist aware of
Oerested experiment, did an experiment to see if magnetic
field can produce electric current. His experiment proved
Electric Current and Direct-Current Circuit
Flow of electric charge in a conductor is called
electric current. Consider the following conductor,
is amount of the electric charge that passes through
the cross-section area

Then electric current is
Capacitors and Dielectrics.
The simplest way to store electric energy is to separate
negative and positive charges from each other. The
simplest instrument that can be used to do this, is consist
of two parallel rectangular plates of area A that are

Sources of Magnetic Field:
In 1820 Christian Oersted observed that electric current
in circuit causes the deflection in the nearby compass.
He realized that electric current can produce magnetic
field. As we can see in the following Figure magnets line

Electrical Circuits:
When several electrical elements like resistors,
capacitors, batteries, and are connected to each
other by conducting wires, then we say that we have
an electrical circuit.
In order to find current and voltage for each element

In gravitational field we know the work done by

Suppose that some fluid passing through cylinder

In physics 131we learned that there are four
fundamental forces in nature,
1. Strong nuclear force.
2. Electromagnetic force.
3. Weak nuclear force.
4. Gravitational force.
