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.
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.
What does an electromagnet do and how does it differ from a regular magnet?
An electromagnet is a type of magnet that uses electricity to create a magnetic field. It can be turned on and off by controlling the flow of electricity. In contrast, a regular magnet is always magnetic and does not require electricity to function.
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 can produce electricity to make a magnet?
Electricity can be produced by various methods such as generators, batteries, and solar panels, which can then be used to power a magnet.
What is a magnet called when electricity is applied to it?
what is a maganet called when electricity is applied to it
How does a bicycle magnet work to generate electricity?
A bicycle magnet works to generate electricity by creating a magnetic field that interacts with coils of wire in a generator. As the magnet spins with the movement of the bicycle wheel, it induces a current in the wire coils, producing electricity.
What is a way to make a very powerful electro magnet?
Put a magnet into AC electricity
What is one electromagnet?
magnet that is a conductor if electricity
