We consider the generation of magnetic fields around laser speckles in an underdense plasma due to an anisotropic laser heating. It is shown to be an important effect under the conditions previewed for the inertial confinement fusion. The anisotropy of electron distribution persists much longer than the electron collision time and creates a steady source for the quasi-stationary magnetic field. The structure of magnetic field around the laser beam is studied along with the effects of plasma dynamics, speckle intensity profile, and the electron heat transport.
