Is Your Compass Wrong? | Neil deGrasse Tyson Explains...

Is your compass actually wrong? Neil deGrasse Tyson and comedian Chuck Nice explore dynamos, pulsars, and how Earth’s magnetic field changes. Find out why your compass isn’t pointing to the north pole and why magnetic north is always changing. Learn about the dynamo that creates our magnetic field and how it doesn’t necessarily align with geography. We explore other magnetic fields in the universe and how pulsars work. What happens when Earth’s magnetic field flips? What about the magnetic field of the sun?
