What type of material is used for making temporary magnet?
An electo-magnet has an iron core wrapped round with wire coils. When electricity is passed through the coils, the iron core become magnetised, until the electricity is switched off.
How can you tunna piece of iron in to a temporary magnet?
Wrap the iron with many turns of insulated copper wire. Then send a current through the wire. The iron core will become an electro-magnet while the electricity is running.
What is the name of a magnet that has coils of wire carrying current wrapped around an iron core?
"Electromagnet"
When current carrying wire is wrapped around an iron core what can it create?
It creates a magnet and magnetism.
What produces an electric current when a coil of wire is wrapped around an iron core is rotated near a magnet?
an inductor
What is is a temporary magnet made by running electric current around a metal core?
Unit 8, Lesson 7. Do your work.

What type of magnet are produced by running electric through a soft iron core?
temporary magnets Incorrect, it's electromagnetic.
How can you turn a piece of iron into a magnet?
To turn a piece of iron into a temporary magnet, wind a coil of (insulated) copper wire around it and run a DC current through the wire. The iron will become the core an electromagnet -- the one you just constructed. As long as direct current flows through the coil, the iron core will attract ferromagnetic materials.jkghyjy Wrap many coils of lacquered copper wire round an iron nail. When electricity is sent through the coils, the nail becomes magnetised. The iron is an electromagnet as long as the power is on. When a piece of iron is brought near the magnet it also becomes a temporary magnet.
When a current carrying wire is wrapped around an iron core what can it create?
a magnet
When a current -carrying wire wrapped around an iron core what can it create?
a magnet
What is the A magnet that has coils of ccurrent-carrying wire around an iron core?
The current produces the magnetic field; such a magnet is called an electromagnet.

What is the difference between a permanent magnet and a temporary magnet?
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
