The cold, linear, resistive, magnetohydrodynamic (MHD) equations are used to study the dynamics of current accumulation at a three-dimensional magnetic null. The particular null under study is axisymmetric about its so-called spine axis, allowing a decomposition into azimuthal modes labeled by mode number m. Analysis shows that the axisymmetric perturbations (m=0) can lead to a current parallel to the spine axis at the null, while the m=1 mode produces currents orthogonal to the spine axis at… CONTINUE READING
