Eddy Current

Overview

Objectives/Goals The purpose of my experiment is to demonstrate the properties of eddy currents, explore the power of eddy currents, and discover things for myself. Methods/Materials The materials I used when I created this mechanism were: * clear acrylic * screws * washers * vice * clamps * camera * timer * hard drive bearing * hard drive magnets * clear tape I did four experiments for each conductor, each experiment had 10 trials I did each trial and each experiment exactly the same except for the conductor. if the pendulum hit the side I re-ran the experiment. For the distance tests I also moved the magnets closer or farther away. Results I got accurate results that followed my hypothesis. Since I did ten trials for each experiment my data is too large to show in this abstract so see my results below. Conclusions/Discussion My data has definitely shown that the conductors that are solid conduct the best. I see a pattern in my data which is that the fastest trial is the solid conductor then the cut or silted conductor then the trials with no magnets. I also see a pattern in my time distance graph. this pattern looks like exponential growth meaning eddy current increases exponentially as the distance between magnets decreases.
