The concept of an electronic nematic, in which the electronic wavefunctions have different symmetry to the crystal structure, has been proposed to explain several unusual properties of iron-pnictides. One important implication is that the magnetic interactions in a material which possesses electronic nematic order are strongly anisotropic, which can be measured using inelastic neutron scattering. Our group have already uncovered magnetic anisotropy at low temperature, and also just above the Neel temperature in SrFe2As2. However, a particular feature of the proposed electronic nematic model for iron pnictides is that the nematic ordering temperature is predicted to be slightly higher than the Neel temperature. We therefore propose to measure the magnetic fluctuation spectrum at 300K, some 108K above the Neel temperature, in order to provide a critical test of the electronic nematic model
