Magnetic fields are everywhere. They permeate the cosmos. They surround the Earth. A great deal about how magnetism works, including how an existing magnetic field can be amplified, is well understood. But the search for the seed that needs to be amplified has posed a serious challenge in theoretical physics.
Now Dr. Swadesh Mahajan of the Institute for Fusion Studies, and his colleague, Dr. Zensho Yoshida of the University of Tokyo might have identified a mechanism that can explain the origin of magnetic fields in the universe.
