State Faraday's Law of electromagnetic induction, both qualitatively and quantitatively. How is Lenz's Law included in this? (4 marks)

emf= (-) d(magnetic-flux)/dt (1 mark)                                                                Faradays law of induction states that the electromotive force induced in any closed circuit is equal to the negative rate of change of magnetic flux enclosed in the circuit. (1 mark)                                 Lenz's Law gives us the direction of the induced emf. It is included in the 'minus' sign which tells us that the direction of the induced emf produces a current whose magentic field opposses the change which produced it. (2 marks)
