1 .1 Historical Perspective
Materials are so important in the development of civilization that we
associate Ages with them. In the origin of human life on Earth, the Stone
Age, people used only natural materials, like stone, clay, skins, and w

What is a composite Material?
A broad definition of composite is: Two or more chemically distinct
materials which when combined have improved properties over
the individual materials. Composites could be natural or sy

Magnetic field is a force which is generated due to energy
change in a volume of space.
A magnetic field is produced by an electrical charge in
motion e.g. current flowing in a conductor, orbital movement
