Im so confused about electromagnetic induction. Need help please?
I first thought that electromagnetic induction disobeyed the law of conservation of energy since there is another current created by another current by changing it (AC). but then there is Lenz law that says when you have yourself an current and also a changing magnetic flux, there will be an induced current that will make another magnetic field opposing the magnetic field of the other so it does not change the system.
Question is if Lenz law is not obeyed, so there would be no induced current or anything, would there be a created energy out of nothing? How would that be possible? Im so confused! Why doesnt Lenz law or electromagnetic induction does not violate the law of conservation of energy? I mean why have to create another current that would oppose the original current if there would be no energy created from the original current?
