Core memory refers to computer memory that consisted of magnetic cores. This memory is now obsolete and is replaced by semiconductor memory known as main memory.

an wang invented the magnetic core memory.

No computer yet built uses such memory. They use a variety of electronic memory or magnetic memory types (some very early ones used mechanical or acoustic delay memory, but these are very slow and bulky and were rapidly replaced with ferrite core magnetic memory when it was developed).

Magnetic core memory was invented by engineer Jay Forrester at MIT in the early 1950s. This early form of computer memory used small magnetic rings, known as cores, to store binary data by magnetizing them.

Core, I am assuming, means "magnetic core memory". This was an early type of persistent memory used on early computers. You could put a core on a shelf and pull it down for use several years later, and it would still have the data in memory as it was the day you put it on the shelf. Core memory was used as permanent random-access memory on early computers

A very small magnetic doughnut (a single core) would have three wires passed through it. Two wires would be used to set or read the position of the magnetic field of the particular core doughnut. A third wire was used to carry the signal if the field was reversed.

All magnetic fields can be reversed by creating a nearby magnetic field at sufficient strength. Current in one of the address wires was insufficient to cause a change in the magnetic field of the doughnut core. But when both address wires carried current at the same time, the magnetic field generated would flip the field of the core to align with the field produced by the current in the address wires.

When one of these tiny doughnuts switched magnetic poles a current was then introduced into the sensor wire and read as a change that might indicate a 1 or a zero. The machine would then put the core back the way it was to preserve that value stored in that memory location.

All of this wiring using these very tiny doughnuts of magnetic material was difficult and cost a lot of money to produce. It was all they had for permanent storage until transistors came into common use.

A computer memory chip is the device that replaced (in the early 1970s) the magnetic core memory in computers (that had been used since the early 1950s). Magnetic core memory replaced a variety of other forms of memory (e.g. Williams tube CRT memory, selectron tube memory, flood gun CRT memory, mercury delay line memory, magnetostrictive delay line memory, rotating magnetic drum memory, long shift register memory) used by earlier computers.

Computer memory (of any type) serves the function of storing instructions and data inside the computer that it will need frequent and rapid access to.

2ng generation. It used transistors and magnetic core memory

I am not sure which device you are asking about, but one pioneer in the development of computer memory devices is the Chinese-American inventor An Wang. In the late 1940s, he invented the magnetic pulse controlling device; this discovery is important because it is the principle upon which magnetic core memory is based. Another important inventor was Jay Wright Forrester, who also made a major breakthrough in the late 1940s. Forrester invented the random-access magnetic core memory, still in use in most digital computers even today.

no idea, but its called a hard drive. Core memory has nothing whatsoever to do with hard drives. Core memory is more analogous to RAM, but was made of small metal or ceramic rings through which wires were threaded. Applying voltages to the wires changed the magnetic polarity of the rings, allowing them to represent "on" and "off" states. See the Related Link for much more information.

The molten iron and medals inside the earths core are the reasons for the earths magnetic core.

Yes, the core in an electromagnet needs to be made of a magnetic material to enhance the magnetic field strength. When an electric current flows through the coil wrapped around the core, it induces a magnetic field in the core, which in turn creates a stronger overall magnetic field around the electromagnet.

The earth's outer core produces the magnetic field.

An electromagnet typically has a magnetic core, such as iron, and is energized by running an electric current through a coil wrapped around the core. When the current flows, it generates a magnetic field around the core, giving the electromagnet its magnetic properties.

Field core refers to the central part of a magnetic field within a magnetic material. It is where the magnetic properties of the material are most concentrated and influential. Understanding the field core is essential for studying magnetic materials and their behavior.

No it does not

Yes, a wooden core would not affect the magnetic properties of an electromagnet since wood is not a magnetic material. For maximum magnetic strength, it is recommended to use magnetic materials such as iron or steel as the core of an electromagnet.

Magnetic drum memory or magnetic drum storage, a type of computer memory/storage that is now long obsolete.

The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.

The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.

The basic concept of a memory core is as old as ENIAC, but was not developed into anything like the modern memory core until it was added to the Whirlwind I in 1953. The Whirlwind was designed in the late 1940s as a flight simulator, but it was too slow. This is because the only types of memory large enough (2 kilobytes) at the time were mercury delay and electrostatic storage, the former being slower and the latter being too unreliable.

The designers eventually, after years of delay, used a combination of published papers and new magnetic materials to produce a basic memory core.

The strength of the magnetic field increases when inserting a soft iron core into a solenoid because the soft iron core is easily magnetized by the current flowing through the solenoid. This creates alignment of the magnetic domains in the soft iron core, enhancing the magnetic field strength within the core and around the solenoid. Soft iron has high magnetic permeability, which concentrates the magnetic field lines and increases the overall magnetic field strength.

Random Access Memory, as verses Sequential Access Memory (delay lines, magnetic tape, magnetic drum, magnetic disk, etc.)

Replacing the iron core with an aluminum core would weaken the magnetic field because aluminum is not as easily magnetized as iron. The magnetic field strength of the electromagnet would decrease as aluminum has lower magnetic permeability compared to iron.

A solenoid with a core becomes an electromagnet when an electric current is passed through it. The magnetic field produced by the current aligns the magnetic domains in the core, increasing the strength of the magnetic field. This allows the electromagnet to attract or repel other magnetic materials.

magnetic tape

Yes, or at least Mostly Yes. RAM is random (RAM=Random Access Memory) and most forms of RAM today are volatile. But magnetic core memory (from the 1950s, now only available in museums) is not.

the function of core is to provide path to magnetic flux,a core may be armature core or may be transformer core

An electromagnet needs a core to concentrate and direct the magnetic field produced by the current flowing through the wire. The core material helps increase the strength of the magnetic field generated by the electromagnet. Without a core, the magnetic field would be weaker and less focused.

Scientists think the Earth's core contains iron because of the planet's magnetic field. Iron is a magnetic material, and the Earth's magnetic field is generated by the movement of molten iron in the outer core. Additionally, seismic waves and the density of the Earth indicate a high concentration of iron in the core.

If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.

The core is a dense chunck of metal that influence the earths magnetic field.

the core creates a magnetic field

The Earth's magnetic field is generated in its outer core, which is made up of molten iron and nickel. The rotation of the Earth creates convection currents in the outer core, generating a magnetic field that extends from the core into space. This magnetic field helps protect the Earth from the solar wind and cosmic radiation.

In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.

Yes, the Earth does have an iron core. The core consists mainly of iron and nickel, and it is divided into an inner solid core and an outer liquid core. The movement of molten iron in the outer core generates the Earth's magnetic field.

There are two types of storage loops exits in magnetic bubble memory.

it has an iron core

The outer core is responsible for Earth's magnetic field due to the movement of molten iron and nickel in the outer core. This movement generates electric currents, which create a magnetic field through a process called the dynamo effect. The interaction between the Earth's rotation and the convective currents in the outer core sustains the magnetic field.

The Earth's inner core is believed to generate the planet's magnetic field through a process called the geodynamo. This is where the rotation of the solid inner core against the liquid outer core creates electrical currents that, in turn, generate the magnetic field due to the conductive nature of the outer core material.

No, the sun does not have an iron core to generate magnetic poles

Scientists think that the presence of the molten nickel iron layer of Earth's outer core and the spinning of the planet creates the magnetic field through the geodynamo mechanism.

The geodynamo mechanism couples the convection of the liquid metal in the Earth's core with the magnetic field to create the current responsible for the magnetic field.

Other planets with a molten metal core can also have a magnetic field.
