Quartz at the core of Earth's magnetic field paradox

Diamonds used to squeeze a sample to ultrahigh pressures corresponding to those of the Earth's core

For centuries, scientists have wondered why Earth has a magnetic field. It's still a mystery, but by using super-high pressures and temperatures to duplicate conditions at the Earth's core, scientists at the Earth-Life Science Institute at the Tokyo Institute of Technology have discovered that there may be quartz crystals there that help explain how the Earth gets the power to generate its field.
