Are Magnetic Generators Effective?

Admin — Thu, 01 Sep 2011 20:44:50 +0000

I’ve been doing some research trying to find out if magnet generators are effective, and if so where is the best place to purchase the specs to make one.
Supposedly, you CAN build them yourself with very little investment, and they will generate electricity throughout your whole house. I’m just hoping to find someone who has some knowledge, firsthand or otherwise, on the subject.

Two generators use the same magnetic field and operate at the same frequency. Each has a single-turn circular?

Two generators use the same magnetic field and operate at the same frequency. Each has a single-turn circular coil. One generator has a coil radius of 3.8 cm and a peak emf of 1.8 V. The other generator has a peak emf of 3.9 V. Find the coil radius r of this other generator.

Using magnetic force to generate electricity?

So, I understand how electricity is generated via a generator by using magnetism to jump-start a movement in [loose] electrons (like in that of copper); however, how far do the electrons go and is there a finite amount? If they’re moving along the atoms in the copper, what happens at the destination?
Ah, I see.. I understood the loop concept in smaller things that were battery operated, but for whatever reason pictured it differently for generators… Okay… So, the electricity used to power things is really just kinetic energy from electrons jumping from atom to atom? (Sort of like how photons [and other higher energy forms like gamma rays] are generated when electrons jump from energy levels, but instead this is from atom to atom??)

Thanks, again..

When you make electricity, where exactly do the electrons come from?

This was a question from my children and I’m not sure of the answer when I think about it. I know that if you spin a magnet in an magnetic field (or ferrous material work too?) that you’ll produce electricity. Electricity is the flow of electrons. If I think of the large generators that spin at a power company that are making large amounts of electricity, I realize that they are creating gazillions of electrons every second and sending them down the wire. Where, exactly, are these electrons coming from? When I think that electrons have mass (albeit very, very little), then I really wonder…..shouldn’t something be losing that mass? Could a physicist put this in layman’s terms for me?
Wow, what great answers. Each a little different but each a piece of the whole answer. Really a great explanation. Now, how to pick the best answer?

Discuss how powerplants use generators?!? Please help!!?

Discuss how power plants use generators. Include a discussion of how a source of mechanical energy is used and how the generator uses that energy source to produce electricity. Discuss the process used at a power plant to get electricity to your home from something such as burning coal, wind, or moving water.

also:

Suppose that a magnetic force in a motor was not strong enough to move. Describe how the force could be made stronger so that the motor would work?

do electric bicycles with on-the-go rechargeable batteries exist?

such as the peddles being hooked up to the wheels as well as one of those magnetic generators where a coil spins around a magnet that can constantly recharge the batteries and give a small boost to wheel turning? or would the electric output be too small?

Does the Magnetic Generator hype for real?

i have seen a buzz on the internet about the magnetic generator being a new option for alternative energy. I have been doing research but i mostly find websites like http://kalireview.com/MagneticElectricityGenerator/ selling generator plans…it gives some information and shows a video but NOT enough information to convince me.

What i am looking for is a website with information…not one that is selling anything (which means they are bias towards magnetic generators).

if ANYONE knows anything about it…or has actually seen one work…please respond. I dont feel like spending my money on something i dont know much about
