An electromagnetic switch having a movable core is called a?
Solenoid
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.
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
An electromagnetic switch having a movable core is called a?

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.

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.

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.
What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
What are solenoid?
The solenoid of an automobile is associated with the starter system and transfers an electric current into the starter motor to set the engine into operation. When the ignition key is turned, current is released from the battery and travels along an insulated wire into the solenoid. The solenoid then releases a small plunger that creates a connection between two internal electrical posts, sends the current down another wire to the starter and forces the starter motor to spin.In general, a solenoid is an electromagnet with a movable metal core. Any coil of wire with current flowing through it will induce a force moving perpendicular to the wire. In the case of a coil wrapped around a cylinder, this force would be directed along the length (through the center) of the cylinder. As such, if you place a movable ferromagnetic (such as iron, nickel, or cobalt) rod through the center of the coil, it will move when current is applied to the electromagnet. This allows a mechanical action to be controlled by the solenoid.
