An electromagnet can be turned on and off, with an electric current and a magnet can not turn off

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.
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
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.
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.
Electro-magnets
of course not.

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.
Yes, because electromagnets can lose their magnetism.
Yes, electromagnets itself is an artificial magnet.

For a simple electro-magnet use a DC supply.
Lots of things do. For example, relays. (The electronical component)

A loud speaker can use electro magnets and i hope this helps =)
