University of California Presents Earth’s Magnetic Field by Professor Constable

Professor Constable gives a lecture on the Magnetic Fields at the University of California. She is a Geophysicist at the Scripps Research Deputy Director. She was born in Scotland but grew up in Australia completing her undergraduate and Masters degrees in Australia. She provides an excellent and informative lecture as this is her field of expertise.  Of note is that the work is partly funded by NASA.  Following this video is a short video on the sun’s magnetic reversal.
