The Earth magnetic field it's created due movimentation of the iron core material. So I presume it needs to be liquid.

But I bet soon we will have some web believers in a new moviment, claming the Earth's core it's made of cheese. As argument they will ask we to get down there to prove the oposity, and if we can't they will say we can't state they are wrong.
21 century it's the reversal not just of moral and ethic values, but also the reversal of the merit and owner of proof.

Anyway the cheese core belivers will fight the flat Earth belivers, and maybe we get some fusion of both leading to a chesse sandwich Earth moviment.
