A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical...

magnetic-core memory is a form of random-access memory. It predominated for roughly 20 years between 1955 and 1975, and is often just called core memory...

wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes...

the wire. This is called a ferromagnetic-core or iron-core coil. A ferromagnetic core can increase the magnetic field and inductance of a coil by hundreds...

outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field...

20 H. Many inductors have a magnetic core made of iron or ferrite inside the coil, which serves to increase the magnetic field and thus the inductance...

flowing through it. The electric current produces a magnetic field around the conductor. The magnetic field strength depends on the magnitude of the electric...

Similar to magnetic-core memory, magnetic rings (or cores) are used to determine the data of the software. Unlike magnetic-core memory, the cores themselves...

applications like magnetic cores for transformers to suppress eddy currents. Ferrites can be divided into two groups based on their magnetic coercivity, their...

varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical...

machinery, requiring special construction such as laminated magnetic cores or ferrite cores to minimize them. Eddy currents are also used to heat objects...

or primary storage. Archaic synonyms for main memory include core (for magnetic core memory) and store. Main memory operates at a high speed compared...

as unsaturated magnetic cores. Not only do these materials have nonlinear magnetic behaviour, but often there is significant magnetic hysteresis, so there...

deduced mostly from measurements of seismic waves and Earth's magnetic field. The inner core is believed to be composed of an iron–nickel alloy with some...

In electronics, a ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such...

000-word, 24,000-digit magnetic-core storage unit. Each of the planes is divided into two sections of 50 by 40 cores, making 2,000 cores in each section. Each...

magnetic path resistance because the magnetic path must traverse the thickness of the core tube twice: once near the plugnut and once near the core....

offered higher speeds than magnetic-core memory, bipolar DRAM could not compete with the lower price of the then-dominant magnetic-core memory. In 1966, Dr....

pacemakers or other medical implants must not use this magnetic drilling machine.[1] Generally, a magnetic core drilling machine is used on a ferrous material...

offered improved performance over magnetic-core memory, it could not compete with the lower price of magnetic-core memory, which remained dominant up...

saturable reactor. It makes use of magnetic saturation of the core, a non-linear property of a certain class of transformer cores. For controlled saturation characteristics...

Look up core memory in Wiktionary, the free dictionary. Core memory or magnetic-core memory, is a form of random access computer memory used by computers...

magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components, consisting of a circular ring or donut shaped magnetic core...

of magnetic flux necessary for high power production, they must have large magnetic cores. In applications in which the weight of magnetic cores must...

from magnetic-core memory, the principal form of random-access memory from the 1950s to the 1970s. The name has remained long after magnetic-core technology...

that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary...

fluid of the outer core as the principal source of Earth's magnetic field. The average magnetic field strength in Earth's outer core is estimated to be...

alternative to magnetic-core memory developed by Sperry Rand in a government-funded research project. Instead of threading individual ferrite cores on wires...

Look up -core or core in Wiktionary, the free dictionary. Core or cores may refer to: Core (anatomy), everything except the appendages Core (manufacturing)...

reversal is a change in a planet's dipole magnetic field such that the positions of magnetic north and magnetic south are interchanged (not to be confused...
