Are Magnetic Generators Effective?

Thursday, September 1, 2011

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 [...]

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.

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.. [...]

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 [...]

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 [...]

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?

In a solenoid, there will be no magnetic field if there is no ____________________ in the wires of the coil. The statement that a voltage can be induced in a conductor by a changing magnetic field is known as ____________________ law. Large power plants in the United States currently use _________________________ generators.

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 [...]
