Electric Motor power point

2. REVIEW:
1. What are the
factors that affect
electromagnetic
induction?

3. C
MOTOR

4. What is motor?
•Device that
converts electrical
energy into
mechanical energy
using the magnetic
turning effect on a
coil.

5. Define the following:
•Battery – is a
device that is
placed inside a
machine to
supply it with
electricity.

6. Define the following:
Magnet – object
that has the
magnetic ability to
attract objects
made of iron or
other magnetic

7. Define the following:
•Copper wire – a
material or object
that allows
electricity or heat
to move through
it.

8. ACTIVITY 9
MAKING YOUR
OWN ELECTRIC
MOTOR

9. SAFETY PRECAUTIONS:
The neodymium magnet is
many times stronger than the
ordinary disk magnet that can hold
papers on refrigerator doors. Be
careful not to get your finger
pinched between these magnets
and other magnetic materials.

10. Wires can get hot when
connected to the battery
for a long time. Open the
circuit once you are done
with your observations.

OWN ELECTRIC
MOTOR

13. GUIDE QUESTIONS:
Q35. What happens to the
shaped wire once positioned
over the battery’s positive
terminal and with both wire
ends curled loosely touching
the magnets?

14. Q36. What other
observations have you
made regarding your
electric motor model?

15. Q37. What will happen if
the number of
neodymium magnets
used in the model
reduced? Increased?

16. Q38. What are the basic
parts / elements of a
simple electric motor?

17. Q39. Based on the
activity, how will you
explain the operation of
a simple electric motor?
