Magnetic Dipole Radiation From A Sinusoidally Varying Dipole--The Transition/Far Zone

Magnetic Dipole Radiation From A Sinusoidally Varying Dipole--The Transition/Far Zone

2.0 MEG AVI File or 1.1 MEG QuickTime File.

The field lines of a magnetic dipole for the case where the dipole varies sinusoidally in time by 10% in amplitude (20% peak to peak). That is, the dipole is always oriented along the vertical axis, and its dipole moment varies in time in a manner proportional to (1.0 + 0.1 sin(2 Pi t/T) ). The animation runs over one period of the oscillation.
