How do geologists know that the Earth's core is made of iron?
the core is made from iron.
Is an iron hinge magnetic?
Everything made of iron is magnetic.
Why there is no substance formed when sulfur and iron is heated?
no,iron sulphide is made up when sulphur and iron is heated.
What is made up of inner and outer core?
The outer core is made up of liquid iron and nickel.
What gases is the mesophere made of?
iron
What is the iron bar in a relay called?
The armature.
What is the moveable iron bar in a relay called?
The armature.
The movable iron bar in a relay?
It is called an armature.
Why is soft iron used in electric bell?
Soft iron is used as the metallic substance which gets attracted to the electromagnet and a hammer is attached to the armature which strikes the gong when the armature is attracted.
How do you use armature in a sentence?
The children all made a small armature with soft metal rods.
What is an armature made of?
The armature is the part of an electric generator or motor that contains the main current-carrying winding. It usually consists of a coil of copper wire that is wound around an iron or steel core. The coil and core are placed in a magnetic field, which is produced by one or more permanent magnets or electromagnets.
Why are motor armatures laminated?
Motor armatures have to be made of thin laminations of iron to work efficiently.A plain solid iron armature would waste a lot of energy in at least two ways:the magnetic field that is produced by the motor's stator would induce strong eddy currents in the solid armature and as a result the armature would get unnecessarily hotthose same eddy currents would counteract the magnetic field of the stator so that extra energy would have to be supplied to the motor to make it drive its intended load.By using an armature made of very thin iron laminations, the eddy currents can be reduced to an acceptable minimum level, thus avoiding unnecessary overheating of the motor and allowing it operate using the lowest possible supply of current to drive its intended load.
In an electromagnet what turns the drive shaft that does the work?
An iron or steel with wire wound on it turns the drive shaft.
How thick is the covering to the statue of liberty?
The copper sheath is 2.37 mm thick or 3/32 " supported by an iron armature
What is the main material in a motor armature?
Instead of a single piece of metal, the armature is made up of laminated thin metal plates. The thickness of the laminations is determined by the supply frequency. They are approximately 0.5mm thick. For the armature core, silicon steel laminates are used to reduce eddy currents and hysteresis losses.
How does relay works?
Current is supplied to the electromagnet and magnitised and attract the soft iron armature. Then it closes the contact allowing the current to flow.
What is the difference between armature reaction and armature reactance?
armature reactant means loss in armature associated with inductive properties of the coil, while armature reaction include losses due to magnetizing component of current flowing through armature.
