Question

Select true or false for each statement below:

1. [ ] Changing magnetic flux can induce an emf in a circuit.

2. [ ] The magnitude of induced emf (or electric field) is inversely proportional to the time rate of changes of magnetic flux through the circuit.

3. [ ] Lenz's law can be used to determine the direction of the induced emf or current.

4. [ ] An electric field is induced by a changing magnetic flux, even in free space, without a conductor.

5. [ ] Maxwell's four equations, together with the Lorentz force law, give a complete description of all classical electromagnetic interactions.

6. [ ] A large, steady magnetic flux through a circuit induces a large emf.

7. [ ] A motional emf could be generated within a piece of a conductor, as the conductor moves through a uniform magnetic field.

8. [ ] Lenz's law states that the induced current and induced emf in a conductor are in such a direction as to enhance the magnetic flux change that produced them.

9. [ ] An induced electric field is a conservative field, just like a static electric field.
