What layer created earths magnetic field?
Earth's magnetic field is created by the movement of molten iron and nickel in the outer core of the planet. This movement generates electric currents, which in turn produce the magnetic field that surrounds Earth.
The dynamo theory states that Earth's magnetic field is created in what layer?
The dynamo theory states that Earth's magnetic field is created in the outer core layer, where the flow of liquid iron generates electric currents through the movement of the molten metal. These electric currents create a magnetic field around the planet.
How a magnetic field is created and how its strength is affected?
A magnetic field is created by moving electric charges, such as electrons. The strength of a magnetic field is affected by the distance from the source, the amount of current flowing, and the material through which the magnetic field is passing. Increasing the current or using materials with higher magnetic permeability will result in a stronger magnetic field.
How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
What is Earth's magnetic field created in which layer?
Earth's magnetic field is primarily generated in the outer core, which is composed of molten iron and nickel. The flow of this liquid metal creates electric currents, which in turn produce the Earth's magnetic field.
Distinguish between a Magnetic Core Memory and a Semiconductor Memory?

What stores information on magnetic cylinders?
Magnetic drum memory or magnetic drum storage, a type of computer memory/storage that is now long obsolete.
What was full name RAM?
Random Access Memory, as verses Sequential Access Memory (delay lines, magnetic tape, magnetic drum, magnetic disk, etc.)
What memory medium is not used as a main memory system?
magnetic tape
How many types of storage loops exits in magnetic bubble memory?
There are two types of storage loops exits in magnetic bubble memory.
Example of a dynamic memory unit?
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
Does the magnetic memory of rock on the ocean floor change over time?
Yes. The ability of a material to retain magnetism after the magnetizing force is removed is magnetic memory.
What primary storage was used in the first generation computers?
Many different types of memory were used in first generation computers, a few of the most commonly used were:electrostatic cathode ray tubes (DRAM)sonic delay lines (DSAM)electrostatic selectron tubes (SRAM)magnetic drums (NVSSAM)magnetic disks (NVSSAM)magnetic core stacks (NVSRAM)Magnetic core memory eventually became dominate.Second and third generation computers continued to use sonic delay line memory, magnetic disk memory, and magnetic core memory (with magnetic core memory still dominating).Late in the third generation computers solid state memory chips replaced all other types of memory.Fourth generation computers used only solid state memory chips.
What is the meaning of core memory?
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.
Which magnetic memory has the fastest access time?
Drum.
What kind of memory is stored on a hard drive?
it uses a magnetic North/South binary, where a north magnetic pull is a 1, and a south is a 0
Who discovered protein based memory in computers?
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).
