Question
Now toggle the Current Source from DC to AC. You can raise the amplitude of the AC signal to better see the induced effects in the secondary coil.
b) Why is current generated in the secondary coil now?
Now vary the frequency from 5% to 100%.
c) Describe the relationship between frequency and current flow (or voltage as from the voltage meter) in the secondary coil.
4. Select “Generator” along the top
The spinning magnet is called the “stator”.
c) If the water flow ceased and you supplied power to coil causing the stator to spin you would then have a __________________ instead of a generator.
Explanation / Answer
a) Why is no current generated in the secondary coil? : current induced only when there is a varying magnetic field. A stationary coil doesn't have a varying magnetic filed
b) Why is current generated in the secondary coil now? The AC is an alternating form of current and a source of varying magnetic field
What kind of current is being generated? It's AC
Make a statement that relates the number of coils to the amount of power generated: Number of coils is directly proportional to the amount of power generated
If the water flow ceased and you supplied power to coil causing the stator to spin you would then have an electric motor instead of a generator.
