Damping Effect
Eddy currents can cause
'damping effect'. When induced current starts flowing in
small circles it is called eddy current. This current flow
is similar looking to eddies in water hence it was named
eddy current.
Damping Effect can be
properly defined as that effect caused purposely or
naturally to a system that tries to minimize the amplitude
of oscillations of an oscillatory system. Damping can also
be said as "force synchronous with the velocity of the
object" but reverse in direction to it. The Simplest example
of damping is a oscillating
"Simple Pendulum"
as shown in above figure.
F
may be related to the velocity v by
-
F=-CV
where C is the
viscous damping coefficient, in units of newton-seconds per
meter
