对流将太阳光球中颗粒之间的磁通量集中成绳状，平均磁场可达1500 g。局部磁能密度远大于动能密度。对磁场对流放大的理论极限进行了分析，并与观测结果相联系。
Convection concentrates magnetic flux into ropes between granules in the solar photosphere, with average fields of up to 1500 G. The magnetic energy density is locally much greater than the kinetic energy density. Theoretical limits to the amplification of magnetic fields by convection are analysed and related to the observations.
