We investigated experimentally the spontaneous magnetic fields produced when a powerful laser beam interacts with a metallic target. It was observed that the signal consists of two components, fast and slow (B2). It was established that Β ι is due to electron emission. The mechanism that produces B2 is governed by the interaction of the expanding plasma with the residual gas.
