Abstract
To understand the role of the Hall effect during fast magnetic reconnection, hybrid simulations with and without the Hall term in the generalized Ohm's Law are compared, as done originally by Karimabadi et al. (2004). It is found that reconnection with the Hall term is fast, but reconnection in the so‐called Hall‐less hybrid simulations is Sweet‐Parker like (slow) when the resistivity is constant and uniform. These results re‐affirm the importance of the Hall term in allowing fast reconnection in the hybrid model.
