Does Mercury have a solid iron core?
I don't think there is such a thing as a planet having a gas core. Even the gas giants have some solid material at their centers.
Where is the Iron core located in the earth?
You have already answered your own question. The: "Iron Core" is the... Core. And the... Core is located in the center of the Earth.
What is core made of?
Outer core - predominately liquid iron and nickel. Inner core - predominately solid iron and nickel.
What is the core of Venus' made of?
the core of venus is very similar to the core of earth, as it is earths twin planet. therefore the the core of venus is made of the same elements as earths core, iron and nickel, both magnetic and it is these elements that create our magnetic field.
What sphere is made up of liquid iron outside and solid iron inside?
The Earth has an iron core. At the outer core it is so hot that the iron is liquid. At the inner core it is hotter still, but under so much pressure it forces the iron to solidify. Hence: the Earth's core.
Why is the core of a moving coil galvanometer made of soft iron?
The term galvanometer is used to refer to a meter which can measure small currents, usually in the mA (10-3A) or mA (10-6A) range. When a soft iron core is used, the magnetic field lines tend to crowd through the core. It is because soft iron core is ferromagnetic in nature. As a result, the strength of the magnetic field due to the field magnet increases, which in turn increases the sensitivity of the galvanometer.
What is the role of the soft iron core?
In a moving coil galvanometer, soft iron core intensifies the magnetic field through it. this causes maximum number of magnetic field lines to pass through the coil.
What is a moving iron galvanometer?
A moving iron galvanometer is used to intensify the magnetic field by reducing the length of air gap across which the magnetic flux has to pass.
What is the advantage of having a cast iron fireplace grate?
The advantages of having a cast iron fireplace is that you can make a fire, without having to worry about starting a fire. Another advantage of having a cast iron fireplace grate is that they are much saver than normal fireplace grates.
What will happen in the absence of iron cylinder in a moving coil galvanometer?
it will not work
Does Mercury have a solid iron core?

What is an iron core inductor?
what is iron core inductors
What is in the core of the earth?
The inner core is mainly solid iron, with a liquid iron outer core.
Write the construction of a moving coil galvanometer?
A moving coil Galvanometer consists of a coil PQRS which is wound over a non metalic frame having soft iron core in the middle. This Coil Is suspended in b/w a powerful magnet poles N-S with the help of Phosphor Bronze wire. Concave mirror is fixed on d suspending thread upside the coil through which deflection can b noted by Lamp and Scale arrangement. The lower end of the coil is connected by hair spring.
State principle of moving coil galvanometer?
Principle of Working:A Moving Coil Galvanometer works on the Electromagnetic effect of current carrying coil (free to move) being placed in an air-gap between the soft iron core and the strong pole pieces of the magnet.The current following in the moving coil which is the specimen to be sensed or measured results in a generation of a Magnetic Field which is opposite to that of the fixed magnetic pole pieces. And as like poles attract each other results in a generation of small deflecting torque which further deflects the pointer or the mirror attached to the axis of the coil.Construction:Moving Coil:The Moving coil which is free to move is being suspended from a soft metallic (non-magnetic) strip carrying the current specimen which is to be sensed or measured. The Moving coil is being suspended in the air-gap available between the fixed Soft Iron-Core and the fixed pole pieces of the magnet.The Soft Iron Core is used to provide a path of low reluctance so as to focus the magnetic field generated by the fixed magnetic pole pieces towards the moving coil. The use of low reluctance Soft Iron-Core helps to increase the sensitivity of the Galvanometer as well.In many of the Moving Coil Galvanometer Construction Soft Iron-Core pieces are removed and this results in the reduction of the sensitivity of the Galvanometer as a whole. In absence of the soft fixed iron core in the middle of the coil the coil then is narrowed in order to reduce the free air space, this narrowing of the coil results in the reduction of the Moment of Inertia(MI) of the moving coil arrangement. This results in having a good near to critical damping with very less oscillations.The Moving coil consists of a large number of turns wounded on a former which can either be in rectangular or circular in shape. The current carrying coil is made up of a thin non magnetic metal so as to have low resistance and less mass.Damping:Damping in Moving Coil Galvanometer is provided by an Eddy current damping mechanism. The damping is made as such to have a nearly critical damping by setting the device to be between under-damped and critical damped case.Controlling Torque:Spring Control mechanism is largely utilized to provide the suitable controlling torque.
