In this lab we had a tube with magnets that moved back in forth when shaken and within the tube was wires coiled. Faraday’s law states that when changing magnetic fluxes through coiled wires generates electricity through the exchange of currents and voltage. We tracked the number of shakes within 30 second intervals at different rates. We then attached the wires to the NXT and counted the number of shakes in order to measure the voltage. We recorded this three different times at three different rates. The computer recorded the voltage values and then opened them onto an excel spreadsheet. We then used the equation e=m^4/volt and sumof^2 and all of the values to receive the average value from shakes. After we created charts, we found that the faster you shake the greater the voltage. In my eyes this lab was created in order to understand how power can be created by something so simple and to show it as a source.
