About
Snippet
Transformers
and
most
electric
motors
operate
on
alternating
current.
In
such
devices
the
flux
in
the
iron
changes
continuously
both
in
value
and
direction.
The
magnetic
domains
are
therefore
oriented
first
in
one
direction,
then
the
other,
at
a
rate
that
depends
upon
the
frequency.
The replay is still saving.
