Remember playing with magnets when you were a kid and wondered what brought the opposite poles together and especially what kept the like poles apart. It turns out the force experienced is one of the most fundamental in the universe – electromagnetism. Along with gravity and the strong and weak nuclear forces, it comprises the foundation for, well, everything. We spoke about this topic on the podcast, AMSEcast, with Alanna Mitchell, author of The Spinning Magnet: The Electromagnetic Force that Created the Modern World – and Could Destroy It.
