| Abstract: | It is shown analytically that self-generated magnetic fields are modulationally unstable with respect to the uniform state of a plasma; such an instability would localize the magnetic field. This localized magnetic flux may well produce small-scale intermittent magnetic fields in coronal active regions or solar flares. |
