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.
What else can I help you with?
Is aluminium better than iron to make an electromagnet?
trytrytrytrytrytry says iron is magnetic where as steel ios a compound?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? will you eat me??
What metal is used to make a cheesegrater?
Stainless steel is commonly used to make cheese graters due to its durability, resistance to corrosion, and ease of cleaning. The sharp edges of the stainless steel make it ideal for grating various types of cheese.
Is electromagnet used in iron box?
Yes, an electromagnet is commonly used in an iron box. The electromagnet generates heat when electricity passes through it, which then heats up the metal plate at the bottom of the iron box to iron clothes.
What Alloy was once used to make sword blades?
The alloy for sword blades was Damascus steel.
How do you separate aluminium and steel cans?
Aluminium and steel cans can be separated using a magnet, as steel is magnetic while aluminium is not. By running a magnet over a pile of cans, the steel cans will be attracted to the magnet while the aluminium cans will not, allowing for easy separation.
Describe how you think an electromagnet can be used to make a stack of scrapped cars three cars high?
An electromagnet's switched can be turned on, so that it can induce magnetism. Anelectromagnetcaneasilymake a stack of three carsbecausecar body is made a steel. Electromagnet and Steel develop a good power of magnetism.
How are magnets used in electromagnets?
An electromagnet makes a great door lock. The steel in the door will stay put until the electromagnet is turned off.
How magnets are used in locks?
An electromagnet makes a great door lock. The steel in the door will stay put until the electromagnet is turned off.
Can an electromagnet pick up steel?
Yes, an electromagnet can pick up steel. When an electric current flows through the coil of an electromagnet, it creates a magnetic field which attracts magnetic materials like steel. The strength of the magnetic field produced by the electromagnet determines how much steel it can pick up.
What material should you use for an electromagnet?
You should use a ferromagnetic material, such as iron or steel, to make an electromagnet. These materials have strong magnetic properties that are necessary for creating a powerful electromagnet.
Why do you not use steel as the core in an electromagnet?
Steel has high electrical resistance, which limits the flow of electric current needed to create a magnetic field in an electromagnet. Instead, iron is typically used because it can be magnetized easily and has lower electrical resistance.
Why should the core of an electromagnet not be made from steel?
The core of an electromagnet should not be made from steel because steel can retain magnetism and decrease the efficiency of the electromagnet by causing residual magnetism. Instead, materials like soft iron or iron alloys are preferred for electromagnet cores as they can be easily magnetized and demagnetized.
Is the core of an electromagnet a piece of steel in the center of the coil?
no
Is steel bolt a magnet?
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
What kind of magnet can attract steel and iron due to electricity?
An electromagnet can attract steel and iron due to electricity. When an electric current flows through the coil of wire in an electromagnet, it creates a magnetic field that can attract ferromagnetic materials like steel and iron. The strength of the magnetic field can be controlled by adjusting the amount of electric current flowing through the electromagnet.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
How can you make an electromagnet rotate?
To make an electromagnet rotate, you can place it in the proximity of a permanent magnet. When a current flows through the electromagnet, it interacts with the magnetic field of the permanent magnet, causing the electromagnet to rotate. This setup can be used in devices like electric motors and generators.
