I just rode 21 km in 52 minutes, walked 5 km in 53:03, and then rode 23 km home in 1 hour. I'm tired.
Did you know that the unit used to measure the strength of a magnetic field is called a Tesla, and the magnetic flux through a loop of wire is measured in Webers?
Just to put in perspective, 11-13 Teslas describes the strength of the magnetic field in a practical use MRI machine. Our magnets in our project were .527 T each, and we had 4 of them, bring it to just over 2.1 T of magnetic field. However because we were turning them by hand, the change in the magnetic flux over time was a measly .0004 Wb/s. I was greatly disappointed
We were making an electric generator based on Faraday's disc generator, where the motion of a conductor through a magnetic field (or in our case, the motion of a field through a coil of wire) produces a current. We were able to generate about 6 mV of potential with .008 mA of current. That measly amount was not enough to light a LED despite our strong magnets.
We only had 50 dollars to work with as well and less than a week to build it once we had the parts. Still we were able to demonstrate that it produced a current, and that was a success.
Anyways, that's why I haven't said much in the last week or so. Looks like you've been doing well here guys!
