True.

Scientists have a widely accepted explanation—the geodynamo: convection of electrically conducting fluid (mainly molten iron) in the rotating outer core generates and sustains the field. However, many details (exact mechanisms of reversals, fine-scale structure, long-term changes) are not fully understood, so the cause is not completely settled in all specifics.
