Hello, my 13-year-old daughter asked for some help with ideas for a science fair project. I was going to make a buck circuit with knob (pontentiometer) to change the PWM percentage. I want the girls to wrap the wire around the core of the inductor and connect it to the buck circuit and do the power tests. Do you think we need to just buy the inductor(s)?
Does the idea sound reasonable? Anyone know where a good source for the iron core and wire to make the inductor?
Here's the science fair project details:
Question: Can changing the speed (voltage) of electricity from a solar panel increase its power output?
Hypothesis: If I alter the speed of electricity from a solar panel using an electromagnet, can I measure an increase in the solar panels power output?
Control: A solar panel connected directly to a 12 volt battery. Using two meters, measure the voltage and current between the solar panel and the battery. Voltage (V) multiplied by current (I) gives power (P) (in Watts). P=VI
Variable: Connect an adjustable electromagnet between the solar panel and the battery, vary amount of current allowed to flow through the magnet. Using two meters, measure the voltage and current between the solar panel and the battery.
Other: Make two electromagnets, one to demonstrate picking up nails, the other used to vary speed of electricity from a solar panel
