Planetary Magnetic Fields: Jupiter

• Recall that Jupiter rotates with a period of about 10 hours. The  very fast rotation would provide for a strong magnetic field, if there is a fluid, conducting core.

Given the strength and size of Jupiter's magnetic field, there must be a fluid, conducting material lurking inside Jupiter.

• So far the fluid, conducting core has been iron, but that is not true for Jupiter.  We will see what conducting, fluid material lurks inside Jupiter later in the semester.
