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.
What is an example of a situation where it would be best to use certain types of magnets to attract different types of objects?
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
What is the hypothesis of magnets?
The hypothesis of magnets is that they contain invisible forces that attract or repel certain metals based on their polarity. This hypothesis explains the observed behavior of magnets interacting with each other and with magnetic materials.
Do magnets turn into flies?
No, magnets do not turn into flies. Magnets are objects that produce a magnetic field while flies are insects belonging to the order Diptera. They are completely different entities with no relation to each other.
Which magnets can retain their property for a short period of time?
Electro-magnets
Do magnets repel non magnetic materials not including electro-magnets?
of course not.

Why are magnets used?
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
Are electro magnets sometimes called artificial magnets?
Yes, electromagnets itself is an artificial 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.
What supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
What has electro magnets in them?
Lots of things do. For example, relays. (The electronical component)
