This
animation illustrates how an electric motor functions when supplied
with
direct current. In this example, the motor is reduced to its simplest
form: a loop of
electrically conductive metal placed within a constant magnetic field
created by
a permanent magnet in U form (the magnetic field lines are illustrated
in blue).
When a current is passed through the loop, the various segments are
subjected to
the effect of the Laplace force (indicated in black) and driven in
a rotary movement
(motor effect). By clicking on the appropriate button, it is possible
to inverse
the supply + and - poles and change the current flow direction.
This, in turn, inverses the Laplace force and consequently the direction
of rotation.
The speed of rotation may also be adjusted using the slide bar.
