Yes. Electromagnets don't require a magnetic material; they just require a conductor and an electric current.

How can you test if a material is magnetic?
Using a compass; You move the compass around the object and if the hand in the compass goes mad, then it is a magnet To test how something is magnetic: See if it sticks to a magnet. It will only be magnetic if it is made from nickle, iron or cobalt. Steel is also magnetic because it is made mostly from iron. Hope this helps x
What is the difference between magnet and magnetic and magnatism?
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
How do magnetic sweepers work?
They work by using a magnet.
What is the separation method using a magnet called?
Magnetic Seperation
Why does using a magnet to separate iron filling from sawdust work?
Iron is magnetic; so, the iron filling is pulled/ is attracted to the magnet. The sawdust is not magnetic, so it will stay where it is, and will eventually be separated from the iron and the magnet.
What instrument measures direction using a magnet?
This could describe a magnetic compass.
What is one of using a bar magnet as a model of earths magnetic field?
HHSHHS
Process of separating iron fillings from a sulfur powder using a magnet?
If you put the magnet near the iron fillings, they will be drawn out by the magnetic pull of the magnet.
Can you make a magnet without using a magnetic material Explain?
If you are referring to a magnet as an object that possesses a permanent magnetic field, then yes. There are three circumstances where magnetic fields exist, but not as a result of a permanent magnet. 1. Electric current causes a magnetic field. Thus, any wire carrying a current or even a current without a wire (like a lightning bolt) will be surrounded by a magnetic field. Since electric current is made up of moving electric charges, it is actually true than any moving electric charge creates a magnetic field. 2. It is difficult to observe outside of a scientific laboratory, but when there is an electric field that is varying in time, that creates a magnetic field. Though not easy to demonstrate directly, this turns out the physical phenomena the allows the creation of elecrtromagnetic waves, e.g. like the light we see with our eyes. 3. Thirdly, one can cause materials that are not able to work as permanent magnets to act as temporary magnets. This is the basis for electromagnets. A steel or iron core with an electric current running through a coil surrounding the core will produce a magnetic field. If you simply cut off the power source, the electric current will no longer flow through the coil. No electric current, no magnetic field. When a non-permanent magnet is created, the magnetic field it produces is just the same as the magnetic field of a permanent magnet, until the source is removed and the field disappears. All of these matters together are an essential part of the basics of electromagnetism which describes how and why the phenomena work.
Which method is appropriate for separating a mixture of iron and aluminum?
You could do this using a magnet, Iron filings are attracted to a magnet, aluminium filings are not.Hint: magnetism, investigate the relative magnetic properties of the metals.Iron is a ferrous material, and aluminum is non-ferrous. A magnet would separate the two materials as the iron would be attracted to the magnet while the aluminum filings would not. The term ferrous basically refers to any material which contains iron.
How do you make magnet car move?
Using another magnet to push (same magnetic poles repel), or pull (opposites attract).
What is one benefit of using a bar magnet as a model of earths magnetic field?
