TOPIC
The Simple Electric motor
AIM
To design a direct current motor
APARATUS/MATERIAL USED
 Copper wire
 Two round magnets
 Paper tube
 Battery
 Plastic cup
 Black tape7
METHOD
First took my conducting wire and wrapped it around my paper tube to create a coil,
then after coiling the tube with the conducting wire, I wrapped the two ends of the coil
with the conducting wire to hold it in place leaving enough ends on both sides to use
for supporting the coil. I then adjusted the wires so that could hold the coil and matched
the heights. I then took a cup and turned it upside down placing a magnet on top of it
and another one inside the cup against the roof of the cup. I then poked four holes on
the cup, one at the bottom and the other at the top. And then I sand all the ends of the
conducting wire and then connected a battery with the conducting wire making the coil
spin.
I predicted that if I connected a thicker coil, the coil would not turn, but it did turn
provided that the adjustments were solidly stable.
Final product

3. RESULTS
At first our coil did not spin meaning that the motor did not work because we did not
sand the tips of the conducting wire. We kept trying but it did not work. But when we

4. did sand the tips of the conducting wire, our coil vibrated only and did not spin due the
thin wire we used to make a coil. We then created a solid coil using the same thin
conducting wire and the coil managed to spin.
 The coil we created can be used on a conveyor belt
 I personally think reducing the number of coils will result in an increase of the
speed of the motor and this is because from our experiment, we had a heavier
coil but our motor work and the coil was turning slowly.
 If the radius of the coil is increased this will weaken the strength of the magnetic
field thus the speed of the motor will decrease
 In designing a motor, the most important thing is making sure that your coil well-
built and made correctly because the coil can affect the functioning of your
motor.
 I followed instructions on constructing a motor, and I then got an extra
conducting wire and then created a heavier coil to see what effect it had
FOLLOW UP QUESTIONS
1. A car Engine, compressors and wiper systems
2. Engines require most powerful motor because it does a lot of work on the weight
of the car and also needs to be adequate in handling its weight
3. They can change the wire of the coil, use a thinner one, and they can also use
more strong magnets and they can also use a coil with more turns.
4. Since designing a toy, I would consider using light materials such as plastic and
not heavy magnets but the same as the ones we used in class to conduct a
practical as they are small. .
5. The magnetic field
6. The coil becomes an electromagnet when the current flows through it.
