Which of the following statements about electromagnetic induction is correct?
- AA conductor moving parallel to magnetic field lines induces an electromotive force (e.m.f.) in the conductor.
- BThe direction of the induced electromotive force (e.m.f.) opposes the change which produces it.
- CThe induced current is in a direction parallel to the direction of motion producing it.
- DThe induced electromotive force (e.m.f.) decreases when the speed of the conductor moving across the field lines increases.
