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 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 the use iron stand with proper clamp?
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.
How is iron-59 used?
Iron 59 is used in medicine as iron suppliments for people with a lack of iron in their blood stream
Does a magnet stick to zinc?
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.
Why is iron easy to magnetize when used in an electromagnet?
Iron is a magnetic chemical element.
Which of these must be used to create an electromagnet?
coils of wire, iron, and electric current
What is the metal used in iron box?
If it's an iron box then it's iron
Why is iron nail used to make an electromagnet?
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
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.
When can an electromagnet acquire?
electromagnet can be acquired when electricity is passed through the soft iron piece.
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 separate iron fillings?
Use an electromagnet.
Can cast iron be made into an electromagnet?
yes
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
Will iron filing get attracted to an electromagnet when it is switched on?
Yes
What metal would you use for the centre of an electromagnet?
iron
