Size of e.m.f
Physics: Cambridge International GCSE Supplement, topic 4.11.2
Size of E.M.F
We can induce a bigger e.m.f in an electrical conductor (coil of wire) during electromagnetic induction in two main ways.
More coils
- Increasing the number of turns of coils of wire.
Faster movement
- Making the magnetic field change more rapidly by moving the wire or the magnet more quickly.
