If the core slows down due to friction with the mantle, will there be an effect on the magnetic field surrounding the Earth?
The slowdown due to friction is very slow...I do not recall the numbers, but the timemust be VERY long compared to other catastrophes which would visit us in the meantime:)
There have been a slew of large earthquakes around the world lately. Could it be related?
I think the timescales at which any changes in the core's rotation appear are much longer than the average human lifetime. I am not sure if any such connection between earthquakes and the core's (mis)behavious should exist...
