An electromagnet is a device that produces a magnetic field with the use of DC electricity. A simple electromagnet has a coil of wire wrapped around an iron core. A simple experiment would be to wrap a copper wire around an iron nail then connect both ends of the wire to a small battery. You will notice the nail is magnetized as long as the battery is connected.

What happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
What are two ways you can increase electrial energy?
Move a magnet near a conductor of electricity faster. Strike a piezoelectric crystal.
How can electricity produce by using magnet?
Electricity is generated when a piece of conductive metal (such as copper) is passed through a magnetic field (or if the magnetic field is moved around the metal). A generator will have a copper wire in the center, surrounded by a magnet shaped like a torus (donut shaped, wire is in the hole in the middle). The wire is stationary. Electricity is generated when the magnet is spun (moving the magnetic field around the wire). This will generate an AC current (alternating current).
What are some examples of insulators of electricity?
Wood, plastic, glass, --> holds electrons tightly. opposite of conductors.
What makes electricity by letting falling water turn turbines and generators?
The moving or falling water travels through a turbine, causing the turbine blades to spin. This in turn, is used to drive a generator (in simple terms, this is a magnet that spins inside a coil of copper wire). The rotating magnetic field produced by the spinning magnet induces an electrical current in the copper wire hence generating electricity. Please see the related links for further information.
What is the difference between magnets and electromagnet?
an electromagnet is a magnet which is activated by electricity and it ceases to be a magnet once the electric supply is stopped whereas a magnet is a natural magnet which does not need electricity and continues to be a magnet whether it is supplied by electricity or not.
Does a magnet just the word magnet conduct electricity?
no it does not.
Can a magnet be used to produce electricity?
A spinning magnet inside a coil of copper wire will produce electricity.
What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
Can connecting a specific amount of magnet to one of your electric wires reduce the electricity usage?
No. Your magnet will fight the electricity.
How are eltromagnets used in generators?
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
How does a magnet produce electricity?
It is weird
What is a magnet called when electricity is applied to it?
what is a maganet called when electricity is applied to it
How do solar panels turn the sun's rays into electricity?
The heat of the rays turn the generator.The generator has a magnet in it. The magnet is inside a copper ring. The magnet urn and makes friction which makes electricity. The electricity goes to the breaker box at a house.
Why do you get electricity when a magnet touches a wire?
because a magnet has positive charges and is also a allows electricity current ot flow through, by so doing we end up getting electricity
What is a way to make a very powerful electro magnet?
Put a magnet into AC electricity
What magnet is created by electricity?
It is called an electromagnet.
