On saturday, I woke up early to grab some breakfast and read the newspaper. On the front page was an article about potential mass transit systems that would be built in Hawaii. I took a look at these types of rail systems and found that almost every type used some sort of electromagnetics. The railcars were elevated by large magnets which prevent friction, and also make it easier to accelerate the large car. I realized that to move something as heavy as a railcar, it must take an enormous amount of electromagnetics-based knowledge, which is something all the physics B students of Iolani should have by now since the test is tomorrow( something I am still working on)!
