The Secret World of Magnets

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.
