Im so confused about electromagnetic induction. Need help please?

so basically the lenz law says in order not to have change the system, it has to generate or induce a voltage, then creates a current and that current generates magnetic field to cancel out the magnetic field of the original. i got that but..

so this means that if LENZ LAW IS NOT obeyed, there would be energy generated out of nothing? that's what i want to know..and in order not to have an energy created out of nothing, there must be an induced voltage? Please answer thanks very much. appreciated your reply. please go easy on me, im really confused.
