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.

Help in creating renewable energy?

I need to make a relatively new invention for a physics research that’ll help save the environment; so, I thought about doing something regarding electricity. My inspiration was the hamster generator … which then evolved (in my mind) to be a wheel being spun endlessly by magnets, thus creating power. Too bad people have already thought of this idea before I did, BUT STILL I can’t find anyone anywhere with the right instructions for me to follow or make innovations on. PLEASE help me!

Also, magnets are going to lose their magnetic attraction/charge eventually, right? Regardless, I still want to make a magnet-powered generator.

Please help

Can I convert an electric start mower starter into a wind turbine generator?

Admin — Thu, 30 Jun 2011 11:06:36 +0000

I know that electricity is produced from a rotating magnetic current, and a rotating magnetic current is produced around an electrified wire. This starter is designed so that a shaft with copper wire coiled around it has a current passed through it creating a rotational magnetic field that spins the shaft. Is it possible for the rotation of this shaft inside of a magnetic field to produce electricity?

Can you find the flaw in this perpetual motion idea?

A fixed magnet sits at the bottom of a hollow, non-conductive cylinder with its north pole turned upward (into the cylinder). Through a slot near the cylinder’s bottom, another magnet is inserted with its north pole turned downward. Magnetic repulsion pushes the two magnets apart. Since the bottom magnet is fixed, the other magnet must rise, thereby gaining gravitational potential energy.

When the rising magnet reaches the top of the cylinder, it gets toppled out and falls. The gravitational potential energy turns into kinetic energy. The magnet lands on a lever which turns a reciprocating handle on a generator. Each time the magnet lands on the lever, the handle turns once fully around, thus converting the kinetic energy into electricity.

The magnet tumbles back into the cylinder, again with the north pole facing down, and the cycle repeats.

Why can’t this continue indefinitely, with free energy being continuously extracted?

Using magnetic force to generate electricity?

Admin — Tue, 07 Jun 2011 11:07:04 +0000

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..

Can inertia of rotation help a generator work in vacuum/space with no fuel forever ?

Admin — Fri, 03 Jun 2011 11:06:35 +0000

I guess inertia of rotation allows an object rotate forgood till an opposing effective force finishes it & rotation of armature with coiling produces elctricity in magnetic field .In vacuum conditions ,there can be nothing to oppose .
So using the facts can electricity be produced in space forever ?
If no why ?

Is there a device that generates electricity when rotated?

I’m trying to build a small magnetic power generator and I need something that generates electricity when being rotated rapidly.

Is there such thing???

How is electrical energy generated in Dynamic Braking when using AC induction motors?

Admin — Sat, 14 May 2011 20:44:10 +0000

Locomotives that use Dynamic Braking with DC traction motors excite the field coils of the motors and turn them into energy producing generators. AC induction motors don’t have that option since there are no windings on the rotating armature and there are no slip rings. When used as a traction motor, there are short circuited windings on the rotating armature that produce magnetic fields when rotated in magntic flux fields produced by three phase rotating fields in the outer windings. It would seem that for these traction motors to produce electricity that they must have additional windings on the rotating armature or permanent magnetics installed. Other articles on AC locomotive dynamic braking say that an induction motor is used with no slip rings. If so then how can the traction motor be turned into an alternator?

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

Admin — Mon, 09 May 2011 18:19:19 +0000

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.

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?
