Overview
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.
Syllabus
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
From Mars Global Surveyor
