Don't feel bad, just do an experiment
with a small permanent magnet motor
It will act as a generator
when you spin the shaft. Spin it with the motor not connected to anything, then connect the leads together and try spinning it again.
When I was in high school
I was in an honors physics class. We had the bell jar with the semi deflated balloon experiment
. The air got evacuated and the balloon expanded too full size.The smartest guy in the whole class understood why the ballon got big, but he was absolutely baffled at why it didn't float to the top of the jar.
The teacher explained that it was being held down by gravity, but the student kept saying "but there's no air! There's no air in space, right? So there can't be any gravity in there!" After about the third go around, the whole class was laughing out loud and the student still didn't get it.
He was otherwise a straight A student.
I still laugh when I think about it.
(and no, it wasn't me)
