10. Motoring on
Before we begin there are three key words that you will need to be able to clearly distinguish between to make progress. Research and find definitions for the words: motor, generator & dynamo, summarise the definitions as you will need to reference these later.
ACTIVITY: Electromagnets in motion - comparing motor effects
ATL
Critical-thinking skills: Practice observing carefully in order to recognise problems
There are two types of electric motor:
the homopolar motor
the commutating motor
Use the attached instructables pdf to help you make your own working homopolar motor.
Use the attached instructables pdf to help you make your own working commutating motor
Compare the ways in which the two motor designs differ.
Summarize how they each produce continuous motion from interacting electromagnetic fields.
