Joel is correct; flux is an ambiguous term. Flux density is not. In
astronomy flux means energy transferred per unit time per unit area
perpendicular to the direction of propagation. I don't like it, but
I can't change it. In SI magnetic flux is measured in webers. The
magnetic induction is the magnetic flux density, measured in teslas.

   1 tesla = 1 weber per square meter perpendicular to the field
