Tiny dust particles are attracted to static charges, so if you could get them from the motor to the air intake by the floor, it may help to pick up even more dust. What could you do to get the static from the motor to the floor attachment? Explain your reasoning.
When an excess of either positive or
negative charge is confined into a relatively small volume (far from any excess charge of the opposite polarity) mutual repulsion
occurs between the charges within that
volume.
This repulsion causes the charges to try to
leave the confining volume and fly apart,
releasing energy. This energy is available
to do damage by sparking.
If two neutral
but dissimilar materials are rubbed
together, causing one to become + and the
other -, there will be very little repulsion
energy available on either object while they are close together. Only when they are
separated will a significant of “spark”
energy be stored on each object. In addition to sparking, charged objects may be
attracted to each other (or repelled). There
is always an attractive force between
uncharged conductors (such as sheet metal or even individual dust particles) and
charged objects (such as an insulating
surface that has just had adhesive removed from it).
Hope this helps.Thanks.
