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.
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.
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
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.
Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
The coil would act as if a bar magnet inserted along its axis. So any iron material inserted gets magnetised.

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
When a current-carrying wire is made to form a coil around a piece of iron the device is called?
A solenoid with iron core also known as electromagnet
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 is the sphere of solid material at the center of Earth?
It is composed of an iron and nickel alloy, and is called the inner core.
What is the melted rock near the center of the Earth called?
It's called the liquid iron and nickel of the outer core. There is no layer of melted rock near the center of the Earth.
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.
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.
Which country center of the earth?
The centre of the earth is not a country it is called the core, made chiefly from iron.
What is the mineral that keeps your blood healthy?
you have something called a blood sell it uses its mineral to keep the blood flowing
