Which layer is melted material?
(The layer that is melted material inner core, the inner core can melt iron & nickel.)
Does cobalt come from the earths core?
No. Material cannot travel from the core to the crust.
What material is the inner core made of?
The inner core is made of nickel and iron.
Can INVAR alloy be used as a magnetic core?
Invar can be used as magnetic core material, but there are better choices. Invar is alloyed for its thermal stability. It is iron with a good percentage of nickel. Remember that magnetic core material is usually laminated or is "powdered" in a way to electrically isolate the "bits" of core material so eddy currents will be reduced. A link is posted to the article on Invar put up by our friends at Wikipedia, where knowledge is free.
Produced when the outer core of a star explodes after the core collapse?
A black hole or a neutron star, depending on the mass of the remaining core. Also a lot of material is ejected into space.
What was the nuclear core of the atomic bomb?
fissile material: highly enriched uranium or plutonium
An electromagnetic-induction device usually has what material in its core?
Iron
What continues the reaction of a boosted fission fusion bomb?
A boosted fission device uses a hollow sealed fissile core. The hollow part contains a measured amount of tritium gas. When the fission device is detonated the heat and pressure ignites tritium fusion in the gas. This fusion emits a flood of high energy neutrons, which causes additional fissions in the (now vapor) fissile material, boosting the yield. Such devices can be implemented with a "Dial-a-Yield" feature by allowing different amounts of tritium gas to be injected into the hollow core (more tritium, more neutrons, more yield).
What is elelctromagnets?
Electromagnet is a device consisting of a core of magnetic material such as iron, surrounded by a coil through which an electric current is passed to magnetize the core.
Can more than a critical mass of fissile material be put in the core of an implosion fission atomic bomb without it becoming prematurely critical causing a fizzle?
Yes, this is exactly what was done in the Ivy King test device which produced a yield of 500 kilotons and then entered the stockpile as the MK-18. It used a uranium core containing roughly four critical masses. To keep this much material in a subcritical configuration the core was a hollow thin walled sphere instead of the usual solid sphere. For safety purposes the hollow inside the core was filled with a chain made of an aluminum-boron alloy that was removed automatically by a motor as the last step in the arming sequence (the chain could not be reinserted).
Why were breeder reactors developed?
Breeder reactors were developed to allow use of non-fissile or fertile fuel, such as uranium-238 and thorium-232, instead of fissile fuel, such as uranium-235 and plutonium-239. They do have fissile fuel in them, but they use its neutron flux to convert the non-fissile (fertile) fuel into fissile form, extending the lifespan of the core.
What is the difference between core type and shell type transformers?
The difference is between how the windings relate to magnetic material around which they are wound. If this magnetic material surrounds the windings then the device is said to be a shell type transformer. If the windings cover the exterior of the magnetic material then the transformer is said to be of the core type. Please see the link.
How are uranium and plutonium bombs alike?
Conventional explosives are used to rapidly assemble a subcritical configuration of fissile material into a very supercritical configuration.A pulsed neutron source initiates the chain reaction.Enough heat is emitted to completely vaporize all materials of the bomb.The inertia of the vaporized depleted uranium tamper holds the expanding vaporized supercritical fissile core together for a little while to improve efficiency and yield.About 1 microsecond after initiation of the chain reaction, the fissile core has become subcritical again stopping the chain reaction.A large release of heat, light, blast, radiation, etc. races away from the burst.Details of construction and materials affect all steps above.
Why nuclear criticality accidents weren't explosive like an a-bomb?
The fissile material involved in all of the recorded incidents did not have sufficient density to detonate. In most cases, the heat generated by the reaction caused the material to expand enough that the reaction became subcritical again. Fission bombs use conventional explosives to quickly compress the plutonium core to a very high density so that the entire mass becomes prompt-critical before the core can expand.
Which layer is melted material?
(The layer that is melted material inner core, the inner core can melt iron & nickel.)
What are the colors of the inner core?
If one could construct a boring device with a camera that could survive the heat and pressure of the journey to the inner core, the only color one would see would be a blinding whitish light from the superheated material.
What are the composition of the core?
The core is made up of Iron and Nickel.
