Well First of all, I noticed tons of thread about this in the forums and tons of the same question being asked in all kind of scientific forums. I am pretty sure everyone here hates this topic, and I have got a bad headache from reading all the comments, but just clarify this to me.
"Most of the people who responded to these threads here stated that magnetic forces don't do work and the work we see comes out from electric forces."
Okay I am alright with that but the question arises a bit why do these electric forces have to equal the magnetic force acquired from The equation ##F = qvB ##?
Using this you can prove that the EMF induced in a moving conductor is
## \text{Emf} = \frac{qvBL}{q} = BLv ##
Which agrees with faraday's law of induction
