In an electromagnet why is it a good idea to use insulated wire?

Because bare wire would short out as the wires are touching each other.

What suitable material would you use for the core of an electromagnet?
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.
Do ferromagnetic materials magnetize?
You can magnetize them by placing them near the magnetic field of a metal, this magnetizes them Another way to magnetize a ferromagnet it to wrap a insulated live wire around it, letting each end of the wire touch a + or - side of a bettery. This produces an electromagnet, and it can be turned on or off.
What are insulated wires made out of?
An insulated wire is made of a conductor surrounded by an insulating 'jacket'.
What will happen to the electromagnet when current flows in the wire around it?
A coil of wire in which current is flowing is an electromagnet. If to that arrangement you add an iron core, then the magnet will get stronger.
What type of magnet is created when electric current flows through a coil wire?
electromagnet

Why must you use insulated copper wire for coil of an electromagnet?
So the wire doesn't short itself out. The electricity needs to go through all the windings individually.
Why is wire better than copper wire on an electromagnet?
whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet whty is copper wire not better than wire on a electromagnet
Is a permanent magnet needed to make an electromagnet?
no you just need something metal like an iron nail and wrap a coil of un-insulated wire around it and send a current through the wire.
Why wire in the coils of electromagnets must be isolated?
Presumably you mean 'insulated', rather than 'isolated'? In which case it is rather obvious, isn't it? If the coils weren't insulated, then the individual windings would short-circuit, and the coil itself would short circuit with the core of the electromagnet.
Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
Is a copper wire a ground wire?
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.
When was Phillips Insulated Wire Company Complex created?
Phillips Insulated Wire Company Complex was created in 1898.
What forms electromagnets?
when we take a soft iro core ad coil it with insulated copper wire. then turn on the circuit.now it will become an electromagnet. it will attract peices of iron steel nickel and cobalt this is an electromagnetic force.
What are the arrangement of moving magnets and wire coil called?
electromagnet
