A solenoid with a ferromagnetic core is called a(n)?
Loadestone
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.
What are four factors that can be varied to change the strength of two magnets?
increase the current in the solenoid add more loops of wire to the solenoid,wind the coils of the solenoid closer together, use a stronger ferromagnetic material for the core. I hope this answered better than the last rude person.
An electromagnetic switch having a movable core is called a?
Solenoid
What is the effect of putting a ferromagnetic material inside the coil of a solenoid?
It strengthens the magnetic field

A solenoid

It strengthens the magnetic field
A coil that is magnetized only when an electric current flows through it?
Yes true. Even without the iron core as current passes through the coil then the coil would act as a magnetic shell. If the wire is wound in a helical form, then the device is known as solenoid. So with the current in the solenoid it would act as if a bar magnet. If iron core is introduced then the magnetic lines would be concentrated and hence an intense magnet could be produced. The pole of this system will be determined by using 'end rule'.
Electromagnets are created using what?
An electric current flowing in a wire creates a magnetic field around the wire. To concentrate the magnetic field of a wire, in an electromagnet the wire is wound into a coil, with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. A coil forming the shape of a straight tube (a helix) is called a solenoid; a solenoid that is bent into a donut shape so that the ends meet is called 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 ferromagnetic core magnifies the magnetic field to thousands of times the strength of the field of the coil alone. This is called a iron-core electromagnet.
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.
Can increase the strength of an electromagnets field by?
using a stronger ferromagnetic material for the core. :)
