Abstract

According to the origin,the electrical currents in coronal loops can be classified into three kinds:the convective current,inductive current and bootstrap current that are investigated and discussed in this paper.Because the magnetic field configuration in solar coronal loop is much similar to that of the Tokamaks,and in Tokamaks,the bootstrap current plays an important role for their steady operating.We introduce the concept of the bootstrap current into coronal loops and find that there will be existence of a measurable bootstrap current in some coronal loops.This current will affect the instability of loops in a great way.
