An electromagnet creates a magnetic field when an electric current flows through it. This magnetic field interacts with the metal objects, causing them to be attracted to the electromagnet and subsequently picked up. The strength of the magnetic field can be controlled by adjusting the current flowing through the electromagnet, allowing for selective picking up of certain metal objects.
What else can I help you with?
What can a electromagnet not move?
An electromagnet is not able to move objects made of non-magnetic materials, such as plastic or wood. Additionally, if the object is too heavy or the magnet is not powerful enough, it may not be able to move the object.
Why would electromagnet be used in a recycling yard rather than a strong permanent magnet?
Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.
Is a pop can a conductor or insulator?
A pop can is a conductor of electricity. Metal objects like aluminum cans are able to conduct electricity due to their ability to allow the flow of electrons.
What property of light energy helps you see the objects in the night?
Bioluminescence is the property of light energy that helps you see objects in the night, as certain organisms are able to produce their own light. This light emission allows you to see these organisms and objects in low-light conditions.
The name of an object which conducts heat or electricity?
Metals which have free valence electrons conduct electricity and heat. thus they are good conductors.
What can a electromagnet not move?
An electromagnet is not able to move objects made of non-magnetic materials, such as plastic or wood. Additionally, if the object is too heavy or the magnet is not powerful enough, it may not be able to move the object.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
Why would electromagnet be used in a recycling yard rather than a strong permanent magnet?
Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.
How are the magnets able to have zero resistance?
If you mean zero electrical resistance for an electromagnet, this is possible with superconductivity. This can be achieved for certain materials at fairly low temperatures - typically a few kelvin.
Can you use electromagnet in space?
Yes, you would be able to use electromagnets in space.
What makes electromagnet are different from permanent mangets?
electromagnets are made through a conduction of electricity so they can only be used when the electricity is kinetic. while permanent magnets are use able all the time because the metal in it is active.
Is a pop can a conductor or insulator?
A pop can is a conductor of electricity. Metal objects like aluminum cans are able to conduct electricity due to their ability to allow the flow of electrons.
What property of light energy helps you see the objects in the night?
Bioluminescence is the property of light energy that helps you see objects in the night, as certain organisms are able to produce their own light. This light emission allows you to see these organisms and objects in low-light conditions.
What advantages are there in being to turn a electromagnet on and of?
Being able to turn electromagnetic on and off is what separates it from a normal magnet.
What is the term for someone who is able to see close objects but unable to see distant objects?
The term for someone who is able to see close objects but unable to see distant objects is "nearsighted" or "myopic."
Why are steel files generally harder than common metal objects?
Steel files are generally harder than common metal objects because they are made of high-carbon steel, which undergoes a heat treatment process to increase its hardness. This process involves heating the steel to high temperatures and then rapidly cooling it, making the file resistant to wear and able to maintain a sharp cutting edge.
The name of an object which conducts heat or electricity?
Metals which have free valence electrons conduct electricity and heat. thus they are good conductors.
