The distribution function f(ψ) of magnetic flux ψ in plasmoids formed in high-Lundquist-number current sheets is studied by means of an analytic phenomenological model and direct numerical simulations. The distribution function is shown to follow a power law f(ψ)∼ψ -1, which differs from other recent theoretical predictions. Physical explanations are given for the discrepant predictions of other theoretical models.
