- 05:10: ... together produces Earth’s magnetic field through a process called the dynamo effect – or so most scientists accept these ...
- 05:42: ... key is that the dynamo effect doesn’t really create a magnetic field from scratch – instead it ...
- 10:18: ... simulations show that the dynamo effect should indeed produce a large-scale dipole field that spontaneously ...
- 10:40: They simulate the dynamo effect in the outer core quite nicely, and even reveal spontaneous polarity flips.
- 05:42: ... key is that the dynamo effect doesn’t really create a magnetic field from scratch – instead it amplifies, ...
