  • A magnetic field is a picture that we use as a tool to describe how the magnetic force is distributed in the space around and within something magnetic.
    Most of us have some familiarity with everyday magnetic objects and recognize that there can be forces between them. We understand that magnets have two poles and that depending on the orientation of two magnets there can be an attraction \(opposite poles\) or repulsion \(similar poles\). We recognize that there is some region extending around a magnet where this happens. The magnetic field describes this region.
  • Every 10 years, the Census Bureau conducts a national tally of the population of the United States. Then, a few months later, it releases a particularly interesting little bit of trivia: where the center of the country’s population can be found.
    Think about it like this. Back in 1780, there were no states west of the Mississippi, so everyone lived close to the East Coast, by definition. The state with the largest population was Virginia, but the largest city was New York \(as it always has been\). So the midpoint of the country’s entire population in 1790 was calculated as sitting just northeast of Virginia — on the Eastern Shore of the Chesapeake Bay.
    As the country expanded to the west, so did the country’s population center. Even after every state was filled in between the Atlantic and Pacific oceans, the population center kept shifting west and south as Americans moved to the Sun Belt. And so it was that on Tuesday the Census Bureau revealed a new average population center in southern Missouri.
