Mrs. Camp's Class
Horacio and Tim
Our electromagnetic crane is made out of
cardboard, corrugated cardboard, string, copper wire, a thread spool,
paint, a tennis ball, and an iron nail. It is powered by a 9-volt battery.
 \
To move the PSA, we pull the battery
that is in the crane backwards and forward. To lift the PSA we
wind up the string on the thread spool.
When you place the alligator clips
onto the 9-volt battery, it immediately becomes electrically charged
and the paper clips will be able to stick to the nail. Therefore,
we will be able to move the paperclips to different areas.
