Timeline for Electromagnetics in the Classical Era
ca. 900 Legend has it that while walking
BC across a field in northern Greece, a
shepherd named Magnus experiences
a pull on the iron nails in his sandals
by the black rock he was standing on.
The region was later named Magnesia
and the rock became known as
magnetite [a form of iron with
permanent magnetism].
ca. 600 Greek philosopher Thales
BC describes how amber,
after being rubbed
with cat fur, can pick
up feathers [static
electricity].
ca. 1000 Magnetic compass used as
a navigational device.
1752 Benjamin Franklin
(American) invents the
lightning rod and
demonstrates that
lightning is electricity.
1785 Charles-Augustin de
Coulomb (French) demonstrates that
the electrical force between charges is
proportional to the inverse of the
square of the distance between them.
1800 Alessandro Volta
(Italian) develops the
first electric battery.
1820 Hans Christian Oersted
(Danish) demonstrates the
interconnection between
electricity and magnetism
through his discovery that an electric
current in a wire causes a compass
needle to orient itself perpendicular to
the wire.
