In #MESExperiments 50 I measure the drop rates of magnets in attraction, magnets in repulsion, and a nonmagnet when placed in an Atwood machine with the same counterweight. The magnets in repulsion fell 12.11% slower than the magnets in attraction, while the non-magnet fell 3.64% faster than the magnets in attraction. While not conclusive, these results strongly suggest that magnets in repulsion do fall slower in gravity as Boyd Bushman, senior engineer at Lockheed Martin, had claimed. I will perform this experiment at higher heights in the near future so stay tuned!
