We analyse cases when thermal and viscous diffusion processes equally affect the dynamo action and when thermal diffusion processes dominate over viscous ones. The spherical shell is considered to be stratified either uniformly or non-uniformly. In the case of non-uniform stratification, the upper thin subshell is stably stratified and the lower subshell is unstably stratified, while for uniform stratification the whole shell is unstably stratified. In all the investigated cases, the generated magnetic field is dipolar. Workplace Geophysical Institute Contact Hana Krejzlíková, kniha@ig.cas.cz, Tel.: 267 103 028 Year of Publishing 2012
