Which of the following will NOT induce an electromotive force in a loop of wire?

• Changing the magnetic field

• Changing the area of the loop

• Changing the angle between the loop and the magnetic field

• None of the above

It states that the direction of the electric current which is induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial

changing magnetic field.

• Faraday’s Law

• Lenz’s Law

• Maxwell’s Law
