A coil of wire with an electric current in it?
A solenoid. An electromagnet is wire wrapped around a core of iron (usually). The wrapped wire itself is called the solenoid.
A solenoid with a ferromagnetic core is called a(n)?
Loadestone
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
How an unmagnetized metal core is magnetized when it is inserted in a solenoid to make an electromagnet?
The solenoid will create a magnetic field inside the solenoid, running parallel to the length of the solenoid. This will happen with or without any metal core, when the current is running. If there is an iron metal core the solenoid's magnetic field will rotate the atoms in the iron in such a way as to reinforce the solenoid's field. The iron atoms are themselves tiny magnets oriented randomly. When alligned, the tiny magnets add to the original solenoid field to give a much stronger magnet.
An electromagnetic switch having a movable core is called a?
Solenoid
What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
What is a core wrapped in a wire that is carying electric current is called?
A solenoid
What are solenoid valves comprised of?
The solenoid is comprised of a coil, coretube, core and enclosure. These are designed to handle the most demanding fluid control applications.
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
How the magnetic field around a solenoid can be strengthened?
The strength of the magnetic field produced by a current carrying solenoid depends on:The number of turns - larger the number of turns, greater is the magnetism produced.The strength of the current - when current increases, magnetism also increases.Nature of 'core-material' used in making the solenoid - if we use soft-iron as a core for the solenoid, then it produces the strongest magnetism.
A device formed from an iron core wrapped in current-carrying wire is?
That can be a 'solenoid' or an 'electromagnet'.
What is the difference between electromagnet and solenoid?
A solenoid is a coiled wire with an electric current running through it, causing a magnetic field. An electromagnet is almost the same thing except it is much stronger than a solenoid (usually) and, unlike a solenoid, has a soft, iron core.
