The magnetic polarity of our planet is quite unstable.

There are two magnetic polarities, each of which is used to represent either 0 or 1.

The transport generated identical magnetic polarities in its own lower hull and the upper surface of the grid.

It can cause other molecules and bits of matter to take on an opposite magnetic polarity.

McKenna's gaze was drawn back as if by magnetic polarity to the contents of the briefcase.

If the bit was previously 1, then the core changes magnetic polarity.

As with the read, the core at the intersection of the X and Y lines changes magnetic polarity.

"We'll have to solve the changes in magnetic polarity in written storage media that happen over the years," he says.

They generally work on the principle that like magnetic polarities repel each other.

The Lyncathrope destroyed the magnetic polarity of the planet, and took them as slaves.
