why iron is suitable for the core of transformer
1. why iron is suitable for the core of transformer
Answer:
The core of a transformer is made of soft iron because it has high permeability so it provides complete linkage of magnetic flux of the primary coil to the secondary coil. Therefore ithas high coercivity and low retentivity.

Answer:
An electromagnet is formed when a wire in an electric circuit is wrapped around an iron core producing a magnetic field. The magnet that results loses its magnetism if the electric current stops flowing. A generator produces an electric current when a coil of wire wrapped around an iron core is rotated near a magnet.
Explanation:
Thats all if you wana know more i recommend you this book Magnetism and Electricity Flash cards And the real answer is the generator Letter A7. The core is the deepest and hottest layer of the Earth. It is made almost entirely of metal.The core is made of two layers: the outer core, and the inner core. The inner core is mademostly of iron. The iron core is extremely hot--between 5,000 and 7,000 degrees Celsius and ANSWER : the pressure there is so great that it cannot melt and it is solid.

10. try to investigate the effect of using a people core instead of an iron core for an electromagnet
Answer:
Soft iron is commonly used in the manufacture of electromagnets due to its high magnetic permeability, which means it can easily obtain magnetic properties when current is conducted through the core and quickly lose them when current is stopped. This is especially crucial in the case of electromagnets, as they are commonly employed for taking up or carrying iron loads, as well as in electric bells and speakers, where rapid transformation of properties is required. Steel may be used as the core in circumstances when such rapid changes are not required. Steel has a low magnetic permeability, so once it acquires magnetic properties, it retains them for a long period. As a result, steel is frequently employed in the fabrication of permanent magnets.

11. What is the name for a coiled wire that is wrapped around an iron core of the electromagnet? A. GeneratorB. SolenoidC. MotorD. Transformer
Answer:
B. Solenoid
Explanation:
Likewise, what has to happen in a coil of wire wrapped around a block of iron before it becomes an electromagnet? An electromagnet is a coil of wire with an electric current flowing through it. When the wire is coiled around in a cylinder, we call this a solenoid. The solenoid becomes an electromagnet when a current flows through it.
12. this layer of earth is solid iron and nickel a.outer core b.mantle c.inner core d.crust
Answer:
crust,mantle,core
Explanation:
layer of earth
Answer:
A. Outer core
Explanation:
The core is the centre of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel, iron and molten rock.
13. 5. How is outer core different from the inner core?a. Outer core is made up of solid iron and nickel, while inner core is made of liquid iron and nickel.b. Outer core is made up of liquid iron and nickel, while inner core is made of solid iron and nickelc. Outer core has a temperature between 50000C to 7000°C while inner core has a temperaturebetween 4000°C to 5000°Cd. Outer core is the outermost layer of the earth while inner core is the second layer of the earth?
Explanation:
The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten. ... The liquid outer core separates the inner core from the rest of the Earth, and as a result, the inner core rotates a little differently than the rest of the planet.

EARTH'S MAGNETIC FIELDQUESTION
Earth's magnetic field is created within Earth by motion of liquid __in Earth's __?
A. Iron; inner core
B. Iron; outer core
C. Nitrogen; inner core
D. Nitrogen; outer core
ANSWERThe constant flowing of liquid iron inside the outer core of planet Earth generates and enables electric currents to exist. That's why the rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around or throughout the planet.

Answer:
the definition of iron core is (electromagnetic) A core made of solid or laminated iron, or some other magnetic material which may contain very little iron.
21. explain the importance of iron core?
Iron core channels the magnetic flux generated by the current flowing around the primary coil, so that as much of it as possible also links the secondary coil.
22. what is the percentage of iron in the core?
Answer:
around 80%
Essentially, most of the Earth's mass must be located towards the centre of the planet. The next step is to ask which heavy materials make up the core. The answer here is that it's almost certainly made mostly of iron. The core is thought to be around 80% iron, though the exact figure is up for debate.
Answer:
80%
Explanation:
Iron, nickel, and other heavy metals like gold, are what makes up the core of the earth because they are the heaviest of the metals and so sank toward the center of the earth. ... The magnetic field needs a liquid iron core to work and therefore only came into existence after the iron migrated to the core.

25. how are crust and iron core alike?
Answer:
The crust makes up less than 1% of Earth's volume. The Earth's core is at the true center of our planet. ... The Earth's crust and core are separated by the mantle. Both the continental and oceanic crust "floats" on the mantle.
Answer:
Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal. The core makes up about 31% of the Earth. Lithosphere and asthenosphere are divisions based on mechanical properties. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The asthenosphere is partially molten upper mantle material that behaves plastically and can flow. This animation by Earthquide shows the layers by composition and by mechanical properties.
