The Magnetic Universe: The Elusive Traces of an Invisible Forceby J B Zirker
Synopses & Reviews
Magnetic fields permeate our vast universe, urging electrically charged particles on their courses, powering solar and stellar flares, and focusing the intense activity of pulsars and neutron stars.
Magnetic fields are found in every corner of the cosmos. For decades, astrophysicists have identified them by their effects on visible light, radio waves, and x-rays. J. B. Zirker summarizes our deep knowledge of magnetism, pointing to what is yet unknown about its astrophysical applications.
In clear, nonmathematical prose, Zirker follows the trail of magnetic exploration from the auroral belts of Earth to the farthest reaches of space. He guides readers on a fascinating journey of discovery to understand how magnetic forces are created and how they shape the universe. He provides the historical background needed to appreciate exciting new research by introducing readers to the great scientists who have studied magnetic fields.
Students and amateur astronomers alike will appreciate the readable prose and comprehensive coverage of The Magnetic Universe.
Book News Annotation:
Writing for a general audience, Zirker (emeritus, National Solar Observatory) surveys the subject of magnetism in astronomy. Following a discussion of the basic properties of magnetism and how they were discovered, he moves from small to large in describing the magnetic phenomenon of the universe, examining in turn the magnetospheres of the Earth, Jupiter, and Saturn; the role of magnetic fields in the formation of stars; the measurement of magnetic fields in the Milky Way and other galaxies; and the magnetic fields between galaxies, among other topics.
