Poloidal Field Gener<strong>at</strong>ion:– The Mean Field α-<br />
effect/classical α-effect<br />
• Small scale helical convection – Mean-Field α-effect (Parker 1955)<br />
• Buoyantly yrising toroidal field is twisted by helical turbulent<br />
convection, cre<strong>at</strong>ing loops in the poloidal plane<br />
• The small-scale loops diffuse to gener<strong>at</strong>e a large-scale poloidal field
