The Curie point is the temperature above which certain materials lose their permanent magnetic properties.

Solid core of The #Earth is a sphere mainly of iron at about 5,200° C and 3.6 million atmospheres
There is a thing called #CurieTemperature, above which magnetic behavior of substances changes.
Above #CuriePoint -higher temperatures- there is NO #magnetism without an applied external field.
Nobody knows what structure this solid Core is in
It's true that #CuriePoint depends on pressure, but idea is that solid core is not origin of The Earth's magnetic field but liquid external part of Core.
