V: olorado River Run h It (Generator In a generator, an outside source of mechanical motion supplies the energy to move a magnet in a magnetic field. A generator works just like the moving magnet in a magnetic field (as in Part II) .Click on Show Field and observe the moving magnetic field Changing Changing Summary Lenz's Law states that the induced EMF opposes the change in the magnetic field. Imagine you were actually turning the water wheel by hand to generate current.

A transformer with 500 loops in the primary Is this free energy or does and 1000 loops in the secondary is a 2:1 step-up transformer that will double the input voltage. something have to stepped down?

Explanation / Answer

In a generator, an outside source of mechanical motion supplies the energy to move a magnet in a magnetic field. A generator works just like the moving magnet in a magnetic field (as in Part II). •Click on Show Field and observe the moving magnetic field

Changing: Increase Number of Loops

Results: Light shines brighter and brighter

Changing: Increase Outside Source

Results: Light shines the brightest, compass direction varies, and magnetic field changes

Changing: Decrease amount of outside source

Results: Light flashes and the magnetic field moves according to the outside source

Changing: Decrease Outside source even more

Results: Everything slows down, and the light dims as well as the compass direction moves slower. Everything reacts according to the rate of the outside source.

Would the wheel resist motion? Yes

As you worked harder at moving the wheel, you would expect the light to shine brighter.

Explain what is happening in the simulation’s generator and in Hoover Dam in terms of the law of conservation of energy.

In the simulation’s generator and in Hoover Dam in terms of the law of conservation of energy, is that the energy is created using outside sources. And the law of conservation of energy states that energy cannot be created or destroyed.

N = # of turns

A = Area of turns

B = magnetic field

? = angular velocity

Is this free energy or does something have to step down? No this is not free energy, the current must be step down.

Hope this helps :)
