2.  Induction heating is a process which is used to bond, harden
or soften metals or other conductive materials. For many
modern manufacturing processes, induction heating offers
an attractive combination of speed, consistency and control.
 Induction heating is a non-contact heating process. It uses
high frequency electricity to heat materials that are
electrically conductive. Since it is non-contact, the heating
process does not contaminate the material being heated. It is
also very efficient since the heat is actually generated inside
the workpiece. This can be contrasted with other heating
methods where heat is generated in flame or heating
element, which is then applied to the workpiece. For these
reasons Induction heating leads itself to some unique
applications in industry.

3.  It helps to have a basic
understanding of the
principles of electricity.
When an alternating
electrical current is
applied to the primary of
a transformer, an
alternating magnetic field
is created. A source of
high frequency electricity
is used to drive a large
alternating current
through a coil. This coil is
known as the work coil.
See the picture opposite.

4.  In a basic induction heating setup shown at right, a solid state RF power
supply sends an AC current through an inductor (often a copper coil),
and the part to be heated (the workpiece) is placed inside the inductor.
The inductor serves as the transformer primary and the part to be
heated becomes a short circuit secondary. When a metal part is placed
within the inductor and enters the magnetic field, circulating eddy
currents are induced within the part.
 The passage of current through this coil generates a very intense and
rapidly changing magnetic field in the space within the work coil. The
workpiece to be heated is placed within this intense alternating
magnetic field.
 Depending on the nature of the workpiece material, a number of things
happen...
