IstvaÁn Pusztai, Peter J Catto, Felix I Parra and Michael Barnes apologize for errors in their articles 'A current driven electromagnetic mode in sheared and toroidal configurations' published in 2014 Plasma Physics Control Fusion Journal. They feel that the last two sentences of the abstract should be replaced by, 'We use the non-physical high-m ideal kink modes to test the current gradient drive term in the local gyrokinetic code'. The 4th and 5th sentences in the 3rd paragraph of section 1 should be replaced by, 'The gs2 simulations presented here are radially local, meaning plasma and magnetic geometry parameters are assumed to vary linearly across the simulation domain.' The 2nd sentence in the 4th paragraph of section 6 should be followed by, 'However, local codes and theory do not allow a rapid variation consistent with the strong current gradients needed to destabilize an ideal kink mode.'
