The
Secret World of Magnets
by Howard Johnson
2nd edition (2006)
Originally published in 1970 as Discovering Magnetism
 Few
people know that a magnet can fire an energy burst several hundred times
stronger than its base strength, again and again…that similar magnetic
poles often attract, not repel…or that the patterns of iron filings
around a magnet bear little resemblance to the force fields, which are
actually spinning vortices. "Conventional magnetic theory and
real magnetic theory are about as much alike as a Venetian Blind and a
blind Venetian." As the
unofficial "father of spintronics," pioneer researcher Howard Johnson
began investigating magnetism in 1942 as a
graduate student at Vanderbilt University, studying Bohr's work on the
electron. Several patents later, two other scientists -- the
late Distinguished Professor Dr. Gerhard Beyer of Virginia Polytechnic
Institute and Steve Davis -- joined him and together they broke some of the magnetic
code, plotting real-time measurements of dynamical systems to reveal the
startling behavior of magnetic vortices in action. In 1970 he and Dr.
Beyer published these previously unknown properties of magnetism,
just as they found them, in a short book, Discovering Magnetism.
The book also describes Johnson's unique magnetic gate, the basis of his
successful close-looped rotary magnetic motor. This new edition by Cheniere
Press is a source-book for novel experiments, and is suitable for all
ages.
54 full-color pages - 11x8½" (28 x 22 cm) -

Magnetism shows how these plots were obtained, and
demonstrates the magnetic gate in action. Hear pioneer
researchers Johnson, Beyer and Davis discuss their work! |
