Shaping core dynamos in A-type stars: The role of dipolar fossil fields

[Context] Large-scale magnetic fields of Ap/Bp stars are stable over long timescales and typically have simple dipolar geometries, leading to the idea of a fossil origin. These stars are also expected to have convective cores that can host strong dynamo action.
