Magnetic Dipole Radiation From a Dipole That Turns Off
Magnetic Dipole Radiation From a Dipole That Turns Off

1.3 MEG AVI File

The field lines of a magnetic dipole for the case where the dipole moment falls to zero over a time scale T. The specific time dependence of the dipole moment is proportional to (Pi/2-arctan(t/T))/Pi, which is a function which is 1 at t = -infinity and zero at t = + infinity, and falls to zero in a characteristic time T.
