In summary, the conversation discusses the possibility of generating electricity by spinning a coil between two magnets. The consensus is that this is possible, as the magnetic field would cause electrons to flow through the coil. The process is similar to how a generator works, with either a magnet or a coil spinning to create a changing magnetic field that generates an alternating current. It is also mentioned that simply spinning the magnet or coil on its own may not generate any current, and further experimentation or research may be needed to fully understand the process. The conversation ends with a suggestion to look at a simple dynamo or "shake" torch for a visual demonstration of this concept.

yes , the magnetic field would cause electrons to flow . if the coil was spinning

That's how a generator usually works, actually. Either a magnet spinning between coils, or coil between magnets.

Imagine the lines of the magnetic field coming out of the pole of the magnet, and imagine those lines passing through the circular cross sectional area of the coil. If you can make any relative motion between the magnet and the coil, either one of them moving, but in such a way that the amount of that field that passes through that area changes continuously, now more, now less, now more, now less, etc., that's the condition that will generate an alternating current in the coil.

Wasn't sure if you could generate electricity by just spinning magnets within a coil or vice versa as well.

It can be done wrong and generate no current. A cylinder magnet polarized on its longitudinal axis, placed inside a cylinder in line with its longitudinal axis will generate nothing if the magnet is spun around its axis while holding the coil motionless, or vice versa. Spin the coil around its axis and hold the magnet stationary, or even spin them both around their axes will result in no current generation.deanbo said:Wasn't sure if you could generate electricity by just spinning magnets within a coil or vice versa as well.

To quote ICP, magnets, how the **frig** do they work?

You might want to open up a simple dynamo and look for yourself.

You don't need to spin the magnet/coil, it can just move up and down
eg "shake" torches work like that

1. How does creating electricity from magnets work?
Creating electricity from magnets involves the principle of electromagnetic induction. This is when a changing magnetic field induces an electric current in a conductor, such as a wire. When a magnet is moved near a wire, it creates a changing magnetic field which causes electrons in the wire to move, generating an electric current.
2. What materials are needed to create electricity from magnets?
To create electricity from magnets, you will need a magnet, a conductor (such as a wire), and a load (such as a light bulb). The type of magnet and conductor used can affect the amount of electricity generated, as well as the strength of the magnet and the speed at which it moves.
3. What are the benefits of creating electricity from magnets?
Using magnets to create electricity can have several benefits. It is a renewable and sustainable energy source as magnets do not require fuel to produce electricity. It also does not produce pollutants or greenhouse gases, making it environmentally friendly. Additionally, magnets can produce electricity in remote or off-grid areas, providing access to electricity in areas without traditional power sources.
4. What are the limitations of creating electricity from magnets?
While creating electricity from magnets has many benefits, there are also limitations to consider. The amount of electricity produced may be limited by the strength of the magnet and the speed at which it moves. Additionally, the cost of producing and maintaining the necessary equipment may be high. The efficiency of converting magnetic energy to electrical energy can also be affected by external factors such as temperature and humidity.
5. How is creating electricity from magnets used in everyday life?
Creating electricity from magnets is used in many everyday devices, such as generators, motors, and electric cars. It is also used in renewable energy sources such as hydroelectric power plants and wind turbines. In smaller applications, magnets are used in devices such as flashlights, speakers, and credit card readers. Magnet technology is constantly evolving and being explored for new and innovative uses in everyday life.
