1. When the motor below is connected to the battery, the iron bar and copper coil spin in a circle.

If no energy is lost as heat and no electrical energy remains after it runs through the coil, how much of the electrical energy flowing through the copper wire is transformed into mechanical energy?
a tiny fraction of it
half of it
none of it
all of it

Do you have any guesses?

all of it i think

whitemonsterbunny17 · Answer

Well, if no energy is lost as heat, I believe that means that there is a full amount of energy, but it says that by the time it runs through the coil, there is no electrical energy left. You would need electrical energy in order to have mechanical energy, so that would mean that there would be no mechanical energy by the time it would reach the wire. 
That's my reasoning, but I could be wrong.

Why do you say all of it, though?
