Tidal magnetism Flashcards
1
Q
Could “action=reaction have anything to do with the generation of tidal magnetism?
A
Electrical current flow will generate a magnetic field around it. This will also work when highly conductive salty ocean water is swept around by tidal forces
2
Q
Why is this the case?
A
Salty ocean currents are electrically highly conductive
3
Q
What does it generate?
A
As they move through earth’s magnetic field, electrical currents are generated in them
4
Q
What do currents generate?
A
The currents generate a secondary magnetic field: tidal magnetism
5
Q
What is this governed by?
A
Oersted’s law
