What c is the piece of iron inside an electro magnet?
Core
Why is it a good idea to put an iron core in the magnet?
You are probably talking about an electro magnet. For detailed explanations and some good drawings see the link on electromagnets here:
How electro magnet work?
ANY electrical current will be surrounded by a magnetic field. In an electromagnet, this magnetic field is often amplified by an iron core.
Can be produced by electric currents going around?
Sending electricity though a copper wire wrapped round an iron core will create an electro-magnet.
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.
Does a iron core strengthen a electro magnet?
Maybe it can I'm not sure. Why do you ask this question Answers.com is not for people to answer you like if we were mental geniuses. Why don't you ask someone else.
How can you tunna piece of iron in to a temporary magnet?
You can turn a piece of iron into a temporary magnet by stroking it with a permanent magnet in the same direction multiple times. This process aligns the magnetic domains within the iron, creating a temporary magnetic field.
How large is moon's electromagnetic field?
The size of the moons electro-magnetic field is proportional to the composition of it's core(not unlike an iron core from a electromagnet), the insulation of the core to the outer surface(not unlike the outer windings of an electro-magnet) and whatever atmosphere it may have. It is approxamately 83% the size of the Earths electromagnetic-field.
Which mixture would correctly separate sand and iron?
Iron can be separated from sand using a (electro)magnet.
What happens to the iron ruler if it rubs with a magnet?
It will become an electro-magnet which is an temporary magnet. it is because of the induction property, the magnetic effect gets transfered to the Scale. (it can be any piece of Iron)
What are the three important parts of electro magnet?
Battery/iron rod/copper wire.
