What else can I help you with?
What happens when you put a magnet wrapped in cling film nearby iron and sulphur?
The magnet will attract the iron, but will not attract the sulphur.
Would applying current through a coil which has a permanent magnet at its center increase the magnetic field from the magnet?
no. applying an electrical current to a coil wrapped around a magnet would create a force, which would move the magnet one way or another. to fully understand how to position coils and magnets to get the result you want, google the 'right hand thumb rule'
How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Magnetism can sometimes be induced in an iron object by?
1.Stroking it with a magnet 2. Applying a current to a coil of wire wrapped around the iron
What is a nail wrapped around a wire and connected to a battery called?
It is called an electromagnet. When electric current flows through the wire, a magnetic field is created, turning the nail into a temporary magnet.
How does the presence of copper wire wrapped around a magnet affect the magnetic field produced by the magnet?
When copper wire is wrapped around a magnet, it creates an electromagnet. This increases the strength of the magnetic field produced by the magnet.
When a current -carrying wire wrapped around an iron core what can it create?
a magnet
When a current carrying wire is wrapped around an iron core what can it create?
a magnet
What is temporary magnet made up of a wire wrapped around a core?
A temporary magnet made up of a wire wrapped around a core is called an electromagnet. When an electric current flows through the wire, it creates a magnetic field in the core, turning it into a magnet. This type of magnet can be turned on and off by controlling the flow of electricity.
When current-carrying wire is wrapped around an iron core what can it create?
It creates a magnet and magnetism.
What kind of magnet is an electromagnet?
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.
What kind of magnet is electromagnet?
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.
When a electro magnet flows through a coil of wire wrapped around a bar of iron it makes what?
a magnetic field
What is A tempoary magnet made when electric currents flows through a wire wrapped around an iron case?
This is called an elecro-magnet, and it is only magnetized while current is running through it.
Can be produced by electric currents going around?
Sending electricity though a copper wire wrapped round an iron core will create an electro-magnet.
What is the meaning of the word solenoids?
A solenoid is a complex electrical component. It is a cylinder with wire wrapped around it that acts as a magnet when electricity is run through the wire.
What happens when you put a magnet wrapped in cling film nearby iron and sulphur?
The magnet will attract the iron, but will not attract the sulphur.
