The best part of having the magnet implant was discovering invisible magnetic fields when I wasn’t actually looking. The first experience I had with this was walking through the intersection of Broadway and Bleecker in Manhattan. I passed through this intersection a few times before realizing that my finger would tingle at a certain spot. After paying a bit more attention, I realized that I was feeling something underground. At first, I assumed it was a subway car, but later came to the conclusion that it was most likely the subway power generator, or the giant fan that was cooling these generators. After noticing these underground waves at Broadway and Bleecker, I began feeling them all over Manhattan.
