What is the purpose of the soft iron core used in making electromagnet?
The purpose is to enhance the magnetic field - to make it stronger - compared to just using air.
What is a suitable material for the core of an electromagnet?
A coil of something conductive to produce the electromagnetic field is the bare minimum. Most electromagnets also have a ferrous metal (which is magnetized in turn) core or housing as well.
Which metal is commonly used in electromagnet?
From the wikipedia article: http://en.wikipedia.org/wiki/Electromagnet A coil forming the shape of a straight tube, a helix (similar to a corkscrew) is called a solenoid; a solenoid that is bent into a donut shape so that the ends meet is a toroid. Much stronger magnetic fields can be produced if a "core" of ferromagnetic material, such as soft iron, is placed inside the coil. The core magnifies the magnetic field to thousands of times the strength of the field of the coil alone. This is called a ferromagnetic-core or iron-core electromagnet. I will assume that you wish to know the metal that is commonly employed as the core, this depends on the application of the magnet but Soft iron is used for many applications. An easy way to produce a electromagnet is using some copper wire, an iron nail and a battery. For further information on which metal is usually used for cores of magnets can be found at the wikepedia site: http://en.wikipedia.org/wiki/Magnetic_core#Common_magnetic_core_materials.
Why does the soft iron core increases the strength of magnetic field?
Iron core (usually soft iron core) is a highly ferromagnetic material. Ferromagnetic materials allows (and attracts) the magnetic field lines to pass through it. When such a material is used in the electromagnet, the magnetic field lines passing through it increases, thereby, the strength of the electromagnet increases. So my friend, I hope you are satisfied with the answer.
What is the best metal to make an electromagnet out of?
An iron core and copper wire (that is coated with an insulator) are used all the time to make electromagnets.

Why is soft iron used in electric bell?
Soft iron is used as the metallic substance which gets attracted to the electromagnet and a hammer is attached to the armature which strikes the gong when the armature is attracted.

Could a electromagnet use a nickel core in the coil of a wire instead of iron?
It is made of a "soft" metal such is iron because it is magnetised easily and demagnetised easily.Electromagnets are said to be temporary magnets because their magnetism can be controlled ie. attraction or repulsion force can be controlled by switching on and off the current which passes through it. That is, electromagnet can be turned on and off as any other electrical device.If some "harder" metal such as steel is used than it can cause the problem because steel is hardly magnetised and it also demagnetises hardly, so it is not efficient to use.Note! Only ferro-magnetics (materials which can be attracted by a magnet) can be used as a core. Those are iron, cobalt, nickel and steel. But among these iron is almost always used because it is the most suitable core.

Why is iron nail used to make an electromagnet?
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
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.

Is electromagnet used in iron box?
iron box
Why is soft iron named as soft iron?
Soft iron does not retain magnetism. It can be magnetised and demagnetised quickly and easily. Used as a core for transformers. 'Soft' probably relates to it's submission, when exposed to magnetism. It 'gives in' without too much fuss.
Why is soft iron used for the core of an electromagent?
The main advantage of an electromagnet is it can be turned on and off. Iron is a soft magnetic material an therefore looses its magnetism very quickly, if you use a metal like like steel it will not loose it magnetism very easily and even if you turn off the current it will remain a magnet.
