Why is iron nail used to make an electromagnet?
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
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.
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.
Why electromagnet is used for separating plastic bags?
An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.
Does magnet attracts zinc?
no...only magnetic materials can be used as electromagnet...zinc is not a magnetic material
Is electromagnet used in iron box?
iron box
Why can't AC electricity be used to make an electromagnet?
In an electromagnet, the negative side of the coil is said to "emit" the magnetic field lines- it is the north pole of the electromagnet. However, in alternating current, the energized wire alternates between positive and negative. As a result, a conventional electromagnet running on alternating current would constantly be undergoing a reversal of the poles.
Is there such a thing as a round magnet?
Magnets can be in any shape. You can have a sphere of iron and magnetize it. I don't believe it is commonly used in practice, but it is certainly possible.Magnets can be in any shape.

Which of these must be used to create an electromagnet?
coils of wire, iron, and electric current

How does the electromagnet used in separators?
Electromagnets are used to separate ferrous metals (containing iron) and attracted to a magnet, from non-ferrous metals (not containing iron) which are not attracted to a magnet.
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.
How can you magnetize iron oxide?
It has been found that iron oxide can be magnetized if it is the right kind of iron oxide. We know that iron (III) oxide (Fe2O3) is magnetic, and it can be combined with just a little bit of other stuff to make ferrite, which is commonly used to make magnets.
Why is a soft iron core used in a relay coil?
because it can magnetize and demagnetize easily
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.
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.
