Core memory, magnetized memory using tiny magnetic rings suspended on a grid of wires, is now more than five decades obsolete, yet it exerts a fascination for hardware hackers still. Not least ...

Mars' magnetic mystery may finally have a solution—scientists now think the Red Planet’s ancient magnetic field only existed ...

The reason they have that name is that magnetic core memory was the primary storage for computers back in the old days and many of us still refer to a computer’s main memory as “core.” ...

The first non-volatile memory that was widely used. Core storage held magnetic charges in tiny ferrite cores, and the direction of the flux determined the 0 or 1. Developed in the late 1940s by Jay W.

Modern data storage relies on magnetic materials to store data ... consisting of magnetic moments rotating around a central ...

Core storage lasted for about two decades, before dynamic RAM (DRAM) chips replaced it, but it is the reason memory was called "memory." The magnetic cores held their content without power (see ...

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...
