    Drag Dynamo
AI Thread Summary
The discussion centers on whether adding a coil to a dynamo increases resistance and creates drag on the rotary mechanism. It highlights that the presence of a coil generates back EMF, which inherently introduces an opposing force to the rotation. This resistance is necessary for the generation of electricity, as mechanical generators always encounter some form of opposing force. The conversation emphasizes that without this resistance, the concept of free energy would be possible, which contradicts established physics. Ultimately, the presence of a coil does add drag due to the generation of electrical energy.

I was wondering;

Imagine two situations:

1) I rotate an axle with a strong magnet attached within a conductive coil (a dynamo).
2) I rotate an axle with a strong magnet attached without a conductive coil.

Does the presence of a coil (and therefore the generation of current in the coil) add any drag to the rotary mechanism, or is the dynamo simply harnessing a form of energy potential that would have been lost otherwise?

Traditionally, it's called "back EMF"
Conceptually, one can consider the well established fact that the generation of electricity(actually, movement) with a mechanical generator REQUIRES resistance to that generation.
That is, in ALL cases of mechanical electrical generators, there will be an opposing force.
If it were not the case... Free Energy!
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
