Edit: ELECTRICAL field sorry

A long-sought invisible force wrapped around Earth has been detected more than half a century after it was first hypothesized.

99% chance I'm being an idiot here, but, compass?

I think it means the electric field created within Earth's atmosphere that is responsible for lightning as opposed to the (electro)magnetic field which forms the magnetosphere around Earth and makes compasses work.
