∙ 15y agoOrdinary steel is not so effective as soft iron because its permeability is lower. Special steel for electromagnets and transformer cores can be made.
Electrical steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel, is specialty steel tailored to produce certain magnetic properties, such as a small hysteresis area (small energy dissipation per cycle, or low core loss) and high permeability. The material is usually manufactured in the form of cold-rolled strips less than 2 mm thick. These strips are called laminations when stacked together to form a core. Once assembled, they form the laminated cores of Transformers or the stator and rotor parts of electric motors.

∙ 12y agoIt is desirable in an electromagnet that the magnetic field will cease when the current flowing through the electromagnet coils stops. If steel is used there is still some residual magnetism when there is no current through the coils. This is an unwanted effect. On the other hand when soft iron is used the magnetic field vanishes when the current stops.

∙ 12y agoyes,aluminium is better than iron to make electromagnet because aluminium posses good thermal expansions.
Wiki User
∙ 11y agoYes, one of the best.

How do you make Aluminum rust?
Aluminium does not rust. Iron is the only metal that rusts.
Why steel is not used to make electromagnet?
for an electromagnet, you need a core material with low remnance. That is, when you remove the magnetomotive force (current in the coil) the core will (mostly) demagnetise and let the load or armature go. Iron or silicon steel has this property. Other steel alloys do not necessarily have this property. They have a high remnance which means they remain highly magnetised even wjen the mmf is removed. This is an undesirable property for an electromagnet.
Why is aluminium used in the central core in power cables?
Aluminium is a) strong b) light c) fairly cheap d) not a terrible conductor of electricity. It's much stronger, lighter, and cheaper than any material that conducts electricity significantly better than aluminium does.Why is that important?Well, if you're making wires for long-distance power transmission, having the wires be strong and light means you can put the towers further apart, which is a significant savings. In fact, aluminium is SO light that you can make the wire thicker (which makes it even stronger), and since power-carrying-capacity increases with increased cross-sectional area, the fact that it doesn't conduct as well as, say, copper becomes less important. And aluminium is so much cheaper than copper that even the thicker aluminium wire is cheaper than a copper wire of the same carrying capacity.
Why do you use an iron in an electromagnet?
Well... the electromagnet has a magnetic field around it which will then attract the paper clips, depending on how much strength the electromagnet has. Also the current flowing in the coil [wires] will make the nail or the electromagnet magnatise.
What is aluminum and iodine make?
Is make Aluminium Iodide, yeah.
Which metals would make the best electromagnet core?
iron
What is used to make aeroplanes aluminium or iron?
aluminum
How do you make an electromagnet field stronger?
You could either put a bar of iron in the center of the electromagnet, increase the voltage that you put in, or make more loops of wire.
What is a better conductor copper or iron?
Given the context of your question i can only assume you are referring to the CORE of an electromagnet. In that case, the more dense the magnetic material you are using the better. In the case of Copper,while dense, it's very weakly magnetic and does not make an effective core. Steel is an alloy and while harder than Iron, is not as dense. Iron, being a denser magnetic material, makes a very effective core for an electromagnet to wrap your insulated copper wires around. I would suggest using Iron; however steel should also work for the purposes of demonstrating the concept of an electromagnet.
How can you make an electromagnet's pulling force stronger?
An electromagnet's pulling force can be made stronger by introducing iron core in it.It increases the magnetic pull.
How does an electromagnet make the sounds you hear in headphones?
It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.
How do you make Aluminum rust?
Aluminium does not rust. Iron is the only metal that rusts.
What alloy does aluminum iron and copper make?
There are some "aluminium bronze" alloys which contain aluminium copper with a small amount of iron and other metals- these are mainly copper with 4-8% aluminium and ess than 1% of other metals.
What three thing are needed to make electromagnet?
Iron, copper wire and dry cell batteries
What makes powerful magnet?
Really powerful magnets are alloys or in some cases not even metals (they're minerals like metal oxides). Iron is one of the better "pure" metals.In alloy or oxide magnets, the metals themselves don't even have to be ferromagnetic; an alloy of aluminium, cobalt, and iron was discovered in 1931 to make far better magnets than iron itself did, even though aluminium is not ferromagnetic at all.
Why is iron nail used to make an electromagnet?
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
What supplies would you need to make an electromagnet?
You need an iron bar, some copper wire and a battery.
