Exploring the Setup of a Magnetic Generator: Magnet Placement and EMF Induction

In summary, the conversation discusses the layout of magnets and coils in a permanent magnet generator and how it affects the generation of EMF. The observation is made that having magnets on both sides of the coils will result in a sine wave output, while placing a magnet in the middle with coils on opposite sides would require electrical contacts for power generation. The suggestion is made to rotate the magnet instead of the coils in this scenario for easier and more efficient operation.

Hi,

I have seen this pdf (http://homepage.ntlworld.com/julien...mic_research/1_permanent_magnet_generator.pdf), on page 2 they show a picture of the stator and rotor discs. From what I can see here, they have magnets on either side of the copper wire coils (top and bottom). I am fairly new to this, so please bear with me.

Is my observation correct? Given that I have 1 coil with two opposite magnets on either side, will this still work like a normal magnetic generator with EMF being AC? Or does having the magnets placed like this change the way the EMF is induced (direction)?

What happens when I place a magnet in the middle, and coils on opposite sides?

Note that the "two" rotors are really one rotor. So as that rotor turns, each coil simply sees a north on top and south on bottom, then it sees a south on top and north on bottom, and then it repeats. So assuming the magnets are mounted fairly close to each other you'll get something close to a sine wave coming out of each coil.

Putting the magnet in the middle and coils on the rotors would still generate some power, but you'd need electrical contacts to get the juice from the coils (and those contacts add friction and also would wear out first, probably).

Thanks fleem. I think in the instance where I have the magnet in the middle I would still rotate the magnet then and keep the coils static, should be easier and better. Thanks for the help.
 

FAQ: Exploring the Setup of a Magnetic Generator: Magnet Placement and EMF Induction

How does a magnetic generator work?

A magnetic generator works by utilizing the principles of magnetism and electromagnetism to create a continuous flow of electricity. The generator consists of a series of magnets and coils of wire that are arranged in a specific configuration to produce the desired electrical output.

What materials are needed to set up a magnetic generator?

The materials needed for a magnetic generator setup include permanent magnets, copper wire, a rotor, and a stator. Other components such as a frame, bearings, and a power source may also be required depending on the specific design of the generator.

Is a magnetic generator a renewable energy source?

Yes, a magnetic generator is considered a renewable energy source because it uses the natural forces of magnetism and electromagnetism to generate electricity. As long as the magnets are functional, the generator can continue to produce electricity without the need for external fuel sources.

What are the advantages of using a magnetic generator?

One of the main advantages of using a magnetic generator is that it produces clean and renewable energy without producing any harmful emissions. It also has a lower maintenance cost compared to traditional generators and can be used in remote locations where access to a power grid is limited.

Can a magnetic generator power an entire household?

It depends on the size and design of the magnetic generator. Some larger and more powerful generators have the potential to power an entire household, while smaller ones may only be able to provide supplemental power. It's important to calculate the energy needs of the household and choose a generator that can meet those requirements.
