I’m very pleased that I now know how to make a motor.
Hopefully someday I can make one that is more elaborate and powerful to power
things of use to me. My handheld motor making skills proved to be on par
because my motor was made in a short amount of time. Not only was it made, but
also it was also very efficient. My motor was constructed using a battery,
paperclips, copper-wire, and a magnet. A motor is made up of a current carrying
wire and a magnet. The battery simply supplied that current. It was the power
source. The paperclips were used for two things; they carried the current to
the copper wire, and they completed the electric circuit. The magnet, which we
later placed in the center of the battery, was basically used to provide the
magnetic field. The copper wire was basically our moving motor. The wire was
coiled and had two pieces extended from the side. These extensions were placed
on the paperclip to complete the circuit. Those extensions had to be scraped.
We had to scrape the extensions off on one side only. This side had to be the
same for both extensions. This particular method of scraping is necessary
because if the whole extensions had it’s plastic coating gone, the coiled wire
would go back and forth, instead of spinning.
Now our
gang sign comes into play. Three finger- thumb, index, middle- point outwards
and correlate to the direction of each factor. This basically describes why the
motor turns. The index finger points in the direction that current flows. The
thumb basically shows the force, or the direction that the motor will turn. The
middle finger represents the direction in which the magnetic field is acting.
With all of this in mind, the force of the magnetic field would be
perpendicular to our current carrying wire. This is why it feels a force and
turns.
My fan
could have been used for a lot. I could have attached a spinning blade to the
motor and two loose wheels on the side of the battery making a mini- lawnmower.
My motor also could have been made into a mini-Segway. I would have had to attach
to wheels to the motor and a place for someone to stand, WA-LA.
