What consists of a coil with an iron core and a movable iron bar?
A solenoid consists of a coil with an iron core and a movable iron bar. The term was coined by French physicist, Andre-Marie Ampere.
What has a wire-wrapped core?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
Does electromagnet consume electricity?
Yes, power is needed: When a current is sent through the coil of wire wrapped round a central core of iron, the iron becomes an electro-magnet.
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 consists of a coil with an iron core and a movable iron bar?
A solenoid consists of a coil with an iron core and a movable iron bar. The term was coined by French physicist, Andre-Marie Ampere.
A what consists of a coil with an iron core and a movable iron bar?
A relay.
What consists of a coil with an iron core and a moveable iron bar?
A relay.
Inserting a soft iron core into a coil has what effect on the inductance of a coil?
increase inductance
What is produced when a coil of wire is wrapped around an iron core?
electromagnet
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.
Why air coil with soft iron core inductance is greater then air coil laminated steel core?
Soft iron has a greater permeability than steel. BTW, the only reason for laminations is to reduce eddy currents in the core. It has no effect on permeability or inductance.
What affects how strong an electromagnet is?
The number of turns in the coil of wire, the electrical current flowing through the coil, and the presence of an iron core inside the coil.
What is a device that has an iron center wrapped in coil of wires?
This is a basic description of an electromagnet. Apply a voltage (direct current) to the coil, and a magnetic field will develop around the coil and be "conducted" through the iron core to create that electromagnet.
Produced by a coil of current-carrying wire wrapped around an iron core?
It makes an electromagnet.
The movable iron bar in a relay is called a what?
A relay is made up of a coil with an iron core and a movable iron bar. The movable iron bar in a relay is called a switch.
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.
