Abstract
In this paper we show that noncommutativity in spatial coordinates can gene rate magnetic field in the early Universe on a horizon scale. The strength of such a magnetic field depends on the number density of massive charged p articles present at a given moment. This: allows us to trace back the tempe rature dependence of the noncommutativity scale from the bounds on primordi al magnetic field coming from nucleosynthesis.
