Planetary Magnetism Science

Explore the fascinating world of planetary magnetism in this 22-minute lecture by Dr. Ramón López. Delve into the physics of dipole magnetic fields, focusing on Earth's magnetic field as a prime example. Discover how internal flows of conducting material generate our planet's magnetic field and learn about its offset dipole nature. Examine higher-order moments and planetary magnetic moments, including insights from the Mars Global Surveyor mission. Gain a comprehensive understanding of planetary magnetism science, supporting the "Lab: Modeling Planetary Magnetism" activity and enhancing your knowledge of heliophysics in an astronomy context.

Physics in an Astronomy Context: Planetary Magnetism
Dipole magnetic field
Earth's magnetic field is basically a dip
Earth's magnetic field is generated by internal flows of conducting material
But it is an offset dipole
There are also higher order momen
Planetary magnetic moments
