They are! Well, sort of... For instance, many small wind-powered generators work by using the wind to spin a wire coil inside of a ring of magnets to produce electricity. Have you seen the flashlights that don't need batteries, the ones you shake up? You are shaking a magnet around a coil of wire! The thing is, it is not really the magnet that is the source of power. When you move a wire through a magnetic field, electricity is produced. But it is really the movement that is the source of energy. If you just lay a magnet next to a wire, no power is produced. You have to move it. In the examples above, it is the wind, or the person shaking the flashlight that is the source of power. So, magnets are very helpful when it comes to producing alternative power, but you still need a source of energy too.
What else can I help you with?
What are magnets that do not require any power of force to maintain their field called?
They are called permanent magnets. These magnets retain their magnetic field without the need for any external power source or force to maintain them.
How many magnets does a flashlight have?
A flashlight does not typically contain magnets. The main components of a flashlight are usually a light source (bulb or LED), a power source (batteries), and a housing for these components.
What power source uses the rotation of giant magnets to create electricity which is then directed to the outlets in people's homes?
The power source that uses the rotation of giant magnets to create electricity is a hydroelectric power plant. In these plants, water flow turns turbines attached to generators with large magnets, which convert mechanical energy into electrical energy that is then transmitted to homes and businesses through power lines.
What are the differences between electromagnets and permanent magnets, and how do they function differently?
Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets that retain their magnetism without an external power source. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
Is wind power an alternate source of energy?
Yes

How do you make high power magnets?
If you already have a medium magnet hook it up to a source energy.
What is a sentence with the word alternate?
I wonder if there is an alternate ending to this film?There must be an alternate solution to this problem.Solar power is an alternate to pollutive coal power.
Which magnets use machines?
Any kind of electromagnet will require an electrical power source, which will typically be generated by a machine of some fashion.

What stops the pulling power of magnets?
I dont think you can ---- If you super-heat the magnets, it will demagnetize them, thus stopping the "pulling power" of the magnets. Basically stick the magnets in a vat of super boiling water, that should be sufficient enough heat to demagnetize the magnets.
Why do big magnets pick up little magnets?
because it is bigger than the little magnets and has more power than the little magnets do.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
How does a perpetual magnet wheel generate continuous motion without the need for an external power source?
A perpetual magnet wheel generates continuous motion without an external power source through the interaction of magnetic fields. The magnets on the wheel repel and attract each other, causing the wheel to spin continuously. This motion is sustained as long as the magnets maintain their magnetic properties.
