Right_Hand_Rule animation
This animated GIF
shows the application of the right-hand-rule (RHR) for the magnetic
force (F) on a current (I) in a magnetic field (B). A wire carrying
conventional current passes through a magnetic field perpendicular
to the field lines. In order to apply the RHR, extend the fingers
of the right hand in the direction of the current in such a
way that when you bend your fingers, they point in the direction
of the magnetic field. Your extended thumb then points in the
direction of the magnetic force on the current. Note that this
same rule applies to the force on a positively-charged particle
if instead of a current in a wire, the particle were traveling
in the same direction as the current in the animation. If the
particle is negative, the direction of the force would be the
opposite of that indicated.
AtmosphericPressure animation
An HTML5 animation
showing how atmospheric
pressure figures into the equation for gaining acceleration to leave
the earth's gravity and fly
into outer space.
Saturn_Flyby animation
A 3D animated GIF
approaching Saturn, flying around the planet showing its rings from
above, below and edge-on. Then you fly into and through the rings
to show they are made of rocks and dust, and are not solid as they
appear, and continue flying up out of the rings, past a Saturn moon,
and away again into space while looking backwards as Saturn receeds.
