Solenoids operate by means of electro-magnetic force when a current is passed through them. Iron is easily magnetised and is the only choice for the core.

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 can you tell the difference between a bar of iron a bar of copper and a magnet?
Iron is a ferromagnetic metal, and copper is not. Iron will be attracted to the magnet but the copper will not.
How many kg is iron bar?
It depends on the size of the bar.
If a 150 gram iron bar is heated to 250c a second iron bar with a mass or 300 grams is heated to 250c which bar has the most thermal energy?
i would say that the 150 gram bar because the thermal energy will be able to travel around the bar quicker
Why would an iron bar rust in the rain?
The iron would react with the oxygen in the water to make iron oxide, or rust.
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 a solenoid may be used to demagnatise a bar magnet?
Heating a bar magnet with solenoid demagnatise it.
Why is magnetism induced into an iron bar placed near a magnet?
A magnetic field induces an electric current. Hence, by placing the iron bar close to the magnet, a current is induced; and so we are, in effect, creating an electromagnet.
If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped
Is an iron bar an insulator or a conductor?
A iron bar is a conductor
Is a iron bar a insulator or a conductor?
A iron bar is a conductor
Is an iron bar a conductor or an insulator?
A iron bar is a conductor
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.
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.
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
What does a magnet field in a solenoid resemble?
a bar magnet
What does the magnetic field in a solenoid resemble?
a bar magnet
