Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north ...
We Earthlings see the sun every day of our lives—but gaining a truly new view of our star is a rare and precious thing. So ...
Wobbly Polarity Is Key To Preventing Magnetic Avalanches On Disk Drives Date: July 17, 2007 Source: University of California - Santa Cruz Summary: New research brings models of magnetic avalanches ...
SANTA CRUZ, CA -- Push two magnets together and you'll set off an avalanche of activity, forcing atoms on each magnet to align their polarity with the intruding magnetic field.
I usually mark a stack of magnets on one side with a sharpie to keep track of polarity, and then use a popsicle stick to scrape one magnet at a time from the stack into the appropriately sized hole.
The Polar Pen — a pen-stylus hybrid housed in a barrel of tubular neodymium magnets — blasted past its CA$14,000 Kickstarter funding goal last month, bringing in a whopping CA$817,164.
Fluctuations in the magnetic field caused by the movement of metallic material in the outer core have brought about full reversals of the magnetic field's polarity in Earth's past.
As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.
The Arbiter Polar 65 Magnetic Gaming Keyboard's magnetic switches let you adjust the actuation distance from 0.1mm to 3.8mm. They also include Rapid Trigger tech that activates a key the moment it ...
Magnets and superconductors go together like oil and water—or so scientists have thought. But a new finding by MIT physicists is challenging this century-old assumption.
Who made the great discovery that if allowed to move freely a magnet pointed north and south is not known, but Peter Peregrinus describes the dual polarity of magnets.
For each bit, a magnetic head grazes a tiny patch of your disk drive, forcing its polarity, or “spin,” to align up or down–the magnetic equivalent of a one or a zero. The patch’s polarity in many ...
