Evolution of Current Loops in Space

  title={Evolution of Current Loops in Space},
  author={Samuel J. Goldstein},
Ampere’s law requires that every magnetic field have an associated current. The analysis of magnetic fields in this paper begins with that current in a circular loop and calculates the forces that make the loop evolve. A circular current generates a dipole field; and a second-order, ordinary differential equation represents the evolving magetic field. The theory describes cases where the conductor shrinks as the loop increases in size. The temperature of the conducting ions and electrons then… CONTINUE READING
