The differences are only weak but it makes for a pretty video at the top of the article: Earth's magnetic ocean tides mapped

Perhaps more interesting is further down in the piece, when it mentions how the magnetic North Pole has been tracked moving from Canadian waters to Russian, at 55km/year:

"This year we are in a rather special situation because in 2018 the magnetic pole will be at its closest to the geographic pole. There is a separation of only 390km. The magnetic pole moves at a speed of about 55km per year," said Prof Olsen. The expectation is that the gap between the two versions of the pole will widen again from next year.
