There is no built-in function for time-averaging, although it is pretty easy to
write one. You should normally average over one period. (Or, technically, you
only need to average over half a period since the flux oscillates twice as fast
as the field.) (Of course, this is only for a time-harmonic field so that you
have a well-defined period.)
