If the variations in the magnetic field occur on scales that are large compared to the gyro-radius of the plasma electrons, the electrons are primarily confined to gyro-centre trajectories along the field lines. Therefore, in-situ electron measurements help us map out the connectivity of the magnetic field in space plasmas. Gyro-centre drifts, wave-particle interactions, trapping, and cross-field diffusion are processes related to field inhomogeneities and"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The transport of electrons in tangled fields results from a complex interplay of plasma processes that occur on a broad range of scales.
