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.
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.
Iron stand can be used as cores for the inside of coils. When mixed with a resin and poured into the center of the coil and let dry, it forms a perfect iron core which allows for quick switching of the magnetic poles as iron does not hold the magnetic charge long. Steel can also be used but it does not release it's magnetic charge as quickly as iron. Iron stand or power can also be used to track magnetic fields also called magnetic flux. By placing a small amount in a transparent box and then placing that box over a magnet, the sand will take the shape of the magnetic field.
Iron 59 is used in medicine as iron suppliments for people with a lack of iron in their blood stream
No. Only to iron and other ferromagnetic materials. Or if you form the aluminum into a coil and pass a current through it, then you have an electromagnet, which would be attracted to a magnet.
Iron is a magnetic chemical element.
coils of wire, iron, and electric current
If it's an iron box then it's iron
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
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.
electromagnet can be acquired when electricity is passed through the soft iron piece.
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.
